Incident 254

Date Jun 07, 2017
Department Buffalo Police Department
Officers Ronald (Ronnie) J. Ammerman , Mark P. Andrzejak , Joseph F. Nigro , Curtis L. Hairston , Charles E. Shelvay , Derrick A. Banaszak , Robert P. Sheridan , Daniel Derenda
Description

Noah Giusiana attended a late-night film at a Regal Cinema in Buffalo, NY with his younger brother. While exiting the movie theater, Giusiana and his brother were “horsing around” and wrestling outside the theater. Giusiana was confronted by a Regal Cinema assistant manager and a brief altercation ensued.

Seconds later, Noah Giusiana was grabbed by off-duty Buffalo Police Officer Mark Andrzejak, who was working as a Regal Cinema security officer at the time. Officer Andrzejak then slammed Giusiana to the sidewalk. An eyewitness heard Giusiana’s head crack when it struck the sidewalk and said that he appeared unconscious as he was lying still, facedown on the ground.

The Buffalo Police department arrived at the scene and placed Giusiana under arrest. The arresting officer at the scene, Ronald J. Ammerman testified that he was never told Giusiana’s head struck the sidewalk. Officer Ammerman’s testimony also revealed that Mark Andrzejak gave false statements regarding Mr. Giusiana’s actions.

AMR attendants asked Giusiana a series of questions and then cleared him to be taken by the Buffalo Police to Central Booking. A cellblock video shows that Noah Giusiana vomited in a sink and slowly slumped to the floor of his cell in Buffalo Police Central Booking around 6:44 AM on the morning of his arrest. Shortly after 9:00 AM, Mr. Giusiana was found unresponsive, lying on the floor of this holding cell. An ambulance was then called and Giusiana was rushed to Erie County Medical Center, where he underwent emergency brain surgery.

Noah Giusiana survived after undergoing emergency brain surgery. However, he is nearly 50% blind, has trouble with his memory, and suffers from other cognitive impairments.

Outcome

After doctors said Noah Giusiana might not live, police charged Jonah Giusiana on June 8, 2017, with felony assault, “for recklessly causing injury” to his brother. Police arrested Jonah while he was visiting his brother at the hospital. An Erie County grand jury reviewed the case, but did not indict Jonah Giusiana. The violations against both brothers were also dropped.

The Buffalo Police Internal Affairs unit began an investigation into whether Andrzejak had used unnecessary force and caused Giusiana’s brain injury. Andrzejak was “exonerated” by the police department. Andrzejak remains a police officer.

Noah Giusiana sued the City of Buffalo, the Buffalo Police Department, seven police officers, Regal Cinemas, off-duty officer Mark Andrzejak, AMR, and two ambulance attendants. Mr. Giusiana’s lawsuit was because the defendants falsely arrested him, negligently caused his injuries, denied him medical care in a timely manner, committed medical malpractice, and failed to train their employees properly.

The Buffalo Common Council approved the payment to Giusiana for $1.05 Million. The remainder of the $2.9 million settlement came from other defendants.

Incident 41

Date Mar 18, 2017
Department Buffalo Police Department
Officers Joseph R. Hassett , Daniel Derenda
Description

Buffalo Police officer Joseph Hassett was recorded on camera assaulting Timothy Stanton Jr. on March 18, 2017. Stanton was taken to ECMC for a head injury and a cut on his forehead that required stitches. The Erie County District Attorney's Office and the Buffalo Police Department both said they didn't learn about the incident until video of the confrontation was requested by Stanton's attorney. Hassett was charged with two counts of third-degree assault, official misconduct, offering a false instrument for filing and making a punishable false written statement in connection to an incident that happened in March 2017.

Prosecutors argued this was excessive use of force, but the Judge disagreed, dismissing all criminal charges. BPD Internal Affairs opened an investigation on May 26, 2017 and officially suspended Officer Hassett on May 30, 2017, according to Commissioner Daniel Derenda. Hassett was suspended for 30 days without pay.

Incident 232

Date Feb 07, 2017
Department Buffalo Police Department
Officers Todd C. Mcalister , Nicholas J. Parisi , Daniel Derenda
Description

Officers Todd C. McAlister and Nicholas J. Parisi tried to handcuff Wardel “Meech” Davis outside a house on the West Side. One of the officers admitted he punched Meech during the struggle, after which the 20-year-old stopped breathing. Meech died a short time later, and even though his death was ruled a homicide, medical records say he died from pre-existing breathing problems that were exacerbated during the struggle.

The officers were not charged and remain on the force. The attorney general said there was "no evidence" to contradict the officers' accounts because there were no witnesses and no video evidence such as body camera footage or dash camera footage. He added that there was "real need of reform" not only with the police department, but also with the Erie County Medical Examiner’s office, particularly because medical officials insisted on checking with police before making their medical rulings on the death.

Incident 261

Date Dec 11, 2014
Time 06:40 AM
Department Buffalo Police Department
Officers Craig J. Leone , Jason M. Mayhook , Earl E. Perrin Jr , Daniel Derenda
Description

Officers armed with guns and a no-knock search warrant raided the wrong home of Maisha Drayton, then a senior director of staff development at the Evergreen Association, a nonprofit health care organization.

Police left all the doors open when they departed, Maisha Drayton testified. Snow from boots were on the floor throughout the house. The warrant left by officers was full of misspelled words, along with the name of a suspected drug dealer Drayton and her kids had never heard before.

Detectives had obtained the search warrant for the home based on the word of an informant facing unspecified criminal charges. The informant told City Court Judge Amy Martoche, who signed the warrant, that she was hoping to “work off some of the charges” when she told police that a man named George lived at the house and had crack stashed inside.

Officers during depositions said they watched the house at least twice before serving the warrant but didn’t see Tariq, then 10, or his brother Xavier, then 16, go to school each morning, nor did they see Maisha Drayton or her husband, who worked as a graphic designer at the Buffalo News, go to work each day and come home each night.

They also didn’t see George, the suspected crack dealer, but that wasn’t cause for concern, police testified during proceedings in the lawsuit. They believed the house was used to stash drugs, not as a point of sale, and so the lack of visible drug activity wasn’t considered unusual for a suspected drug dealer.

The Draytons owned the home where they’d lived for seven years, and police knew it. They also knew that utilities were in Maisha Drayton’s name. That, too, didn’t cause police to question whether the informant had told the truth about George living there.

In seeking a search warrant, Detective Earl Perrin told Judge Martoche that he knew about George and the house before the informant told police that the Drayton home contained cocaine. He asked that the warrant be no-knock because people inside the house had guns. Kirkham wrote that Mayhook wasn’t candid when he told the judge, without corroborating the informant’s information, that the house was used to stash crack sold elsewhere.

“This statement among other representations made to the court at the in-camera hearing for the search warrant constitutes material misrepresentations of the facts that led to a finding of probable cause [to search the house],” Kirkham wrote.

Officers involved in the raid admitted no mistakes during depositions.

Outcome

Due to the raid, Maisha Drayton, who was in underwear when police rousted her from bed, suffers from post-traumatic stress syndrome and has experienced panic attacks and vertigo as well as migraine headaches, her lawyers say. Xavier suffered sprained wrists from being handcuffed, injuries to his arms and shoulders and has also experienced emotional injuries, according to the lawsuit. Tariq, who visited a therapist, suffered emotional injuries and has had nightmares, according to the family’s attorneys.

The Buffalo Common Council settled the Draytons’ lawsuit against police for $255,000.

Incident 231

Date Sep 09, 2014
Department Buffalo Police Department
Officers Joseph R. Hassett , John F. Beyer , Daniel Derenda
Description

In September 2014, Hassett and his partner, John Beyer, apprehended 26-year-old Keith Worthy at a gas station at the corner of South Park Avenue and Louisiana Street. The officers then took Worthy and his car into the nearby Commodore Perry housing projects, according to sources who have viewed the investigations that followed.

The officers charged Worthy with trespassing on public housing property, according to the incident report. They also charged Worthy with leaving his car — which had been at a gas pump before they arrested him and moved it — unattended and blocking a roadway.

Outcome

All the charges against Worthy eventually were dropped.

The Internal Affairs investigation into the incident took four years to resolve. The finding: The complaint was “not sustained.” Neither officer was punished.

Time 06:00 AM
Department Buffalo Police Department
Officers Shawn D. Adams , Joseph M. Cook , Daniel Derenda
Description

On July 29 2014, Buffalo Narcotics officers and the SWAT team stormed a West Seneca residence on Edson Street at 6 am in the morning. The residents were sleeping with their house-dog, a nine month old pit-bull puppy named Rocky, who was beloved both in the house and within the community. Rocky had been trained and loved from the time of his birth, was very well socialized, and did not have a mean bone in his body.

In fact, medical records show that despite the officers frightening method of entry into the residence, all Rocky did was stretch his legs at the foot of Joseph Smith, one of his owners' bed. Photos, police reports, and medical records show that two narcotics officers Detectives Joseph Smith and Shawn Adams shot Rocky numerous times with multiple firearms from over 10 feet away as the innocent dog stretched on Smith's bed.

Outcome

The police found a small amount of drug residue and marijuana in the cubbies of a bedroom and charged Joseph Smith, whose dog was blown up at his feet. Smith’s attorney, after a long legal battle, was able to get the charges against his client dismissed. Despite the thousands of dollars that have gone into this worthless prosecution, the DA doubled downed to protect the dog killers and refilled the charges against Smith

Incident 253

Date May 11, 2014
Department Buffalo Police Department
Officers Adam E. O'shei , Robert Eloff , Michael Beavers , Daniel Derenda
Description

Air National Guardsman William C. Sager Jr. was gravely injured when he was pushed down a flight of stairs by Molly's Pub bar manager Jeffrey Basil. When the incident happened at Molly's, two off-duty Buffalo Police officers were there -- Adam O'Shei and Robert Eloff. Officer Eloff helped drag the unconscious Sager out of the bar after the push and handcuffed him at Basil’s request. After spending weeks in a coma at the hospital, Sager died. He was 28.

The incident occurred during a sad chapter of Buffalo history during which members of the Buffalo Police force were not only allowed to have side jobs working security for the local bars, but they were actually encouraged to do so. Despite knowing that this system created a "breakdown in the chain of command," the City's Police Commissioner felt that having visible police stationed throughout the city's bars provided an added police presence at no cost to the taxpayers.

This policy decision was longstanding, and had produced a plethora of citizen complaints from bar patrons. The practice created a conflict of interest for the off duty police, who developed an allegiance to personnel at the bars they were supposed to be policing. The result was a long list of complaints, including underage drinking, bouncers getting away with being overly aggressive, and in some cases, the off-duty police themselves using excessive force. Although the Police Commissioner acknowledged that he considered ending the program prior to May 11,2014' that suggestion was opposed by the rank and file as well as the police union, and the policy was therefore allowed to continue. After the death of William Sager, the Commissioner terminated the policy. However, the practice of off-duty Buffalo Police Officers being allowed to work security jobs on the side continues to this day.

Outcome

Officer O'Shei was suspended for his involvement in the Molly's Pub incident that led to the death of a national guardsman but did not be face any charges. Eloff pleaded guilty to violating the civil rights of Donald Hall, a friend of Sager. He resigned from the force as part of the plea. Eloff was sentenced to three months in federal prison and three months of home confinement in 2016 in connection to the incident.

In 2015, William Sager Sr., the father of William Sager Jr, filed a civil suit for damages against the City of Buffalo, the Buffalo Police Department, the Buffalo Police Benevolent Association, Buffalo Police Commissioner Daniel Derenda, Buffalo Police Officer Robert Eloff, Buffalo Police Officer Adam O'Shei, Jeffrey Basil, Molly's Pub, the shareholders of Molly's Pub, and Independent Health. The lawsuit continues to be litigated, and is pending trial. In 2015, a friend of William Sager also filed a civil suit for damages against the City of Buffalo, the Buffalo Police Department, Buffalo Police Officer Robert Eloff, Buffalo Police Officer Michael Beavers, Molly's Pub, and the shareholders of Molly's Pub. The lawsuit continues to be litigated, and is pending trial.

Description

Police busted down a door of a Breckenridge apartment belonging to Iraqi War combat veteran, Sgt. Adam Arroyo in Buffalo looking for drugs. In the process, the police shot Arroyo's dog Cindy multiple times, killing the dog.

Police claim they read his address wrong. They meant to raid the upstairs front apartment at 304 Breckenridge St, but they became confused and raided the rear apartment. Busting down Arroyo’s door, they found that he was not at home. His dog Cindy, a pit bull, was tethered to the sink in the kitchen.

Detective Joseph Cook, accompanied by a SWAT team of police, chose to stand beyond the length of tether and shoot Cindy, as opposed to wasting the time it would take to get animal control into the house and place the dog in a kennel.

After Cindy was shot, animal control arrived and unloosened her from her bloodied leash. The impact of the bullet had thrown the dog, and it had become entangled around her neck. They were inconvenienced as they unwound her leash and untethered her, removing her carcass in a body bag.

Without realizing it was not the apartment named on the search warrant, police were inconvenienced as they ransacked the apartment. Blood from the dog got on their boots and, despite wiping it off on the carpet, they spread it all over the apartment. Some of it stuck like plague to their boots.

Incident 26

Date Nov 28, 2012
Time 08:54 PM
Department Buffalo Police Department
Officers Michael J. Anderson , Robert M. States , Matthew Cross , Daniel Derenda
Description

In 2012, Richard A. Metcalf Jr. died from strangulation when jail guards at the Erie County Holding Center secured a spit mask around his neck, leading to suffocation while he was restrained and left face down on a stretcher with the mask and a pillowcase covering his head. Metcalf, aged 35, was transported to Erie County Medical Center and taken off life support after two days.

Outcome

In a civil suit filed by Metcalf’s father, Erie County could have settled over the death of Richard A. Metcalf Jr. for $17 million, but instead took the case to a trial. The trial ended with a jury’s $95 million judgment against the county – the largest known civil verdict ever against the county. Before the lawsuit filed by Metcalf’s father went to trial, the county had already spent $900,000 on legal bills related to the case. Toth said he expects legal costs for defending the county through the trial to total around $2 million.

County Attorney Jeremy Toth called the jury’s decision “inexplicable” and the county would argue the court for a reduced settlement. After arguing for a reduced settlement, a state judge has cut the damages award for the murder of Richard A. Metcalf Jr. from $100 million to $20 million. Acting State Supreme Court Justice Mark J. Grisanti reduced the jury's April award after attorneys for the county and five current and former jail deputies argued that what the jury granted was "excessive."

The jury determined the five deputies used excessive force and four of the five were negligent and violated Metcalf’s civil rights by being “deliberately indifferent” to his medical needs. Jurors in the Metcalf case found that the county and five current and former deputies were liable for using excessive force and depriving Metcalf of proper mental and physical medical care. Among the former deputies that were found to have used used excessive force on Metcalf were Matthew Cross and Robert States, who are now current Buffalo Police Officers. Robert Dee was fired in 2022 by the Sheriff’s Office after a series of investigations into unrelated misconduct, including domestic violence charges and improper contact with a woman who was incarcerated. Edward Kawalek and Scott Emerling still work for the Sheriff’s Office.

Description

Wilson Morales was shot by Buffalo police officers after a car chase on the city’s East Side. The bullet that struck Morales, then a 17-year-old student at WNY Maritime Charter School, instantly paralyzed him from the chest down.

Outcome

Morales, who is still recuperating, faces trial on charges of assaulting a police officer and unlawfully fleeing from a police officer.

Buffalo’s Common Council authorized one of the largest lawsuit settlements in the city’s history: $4.5 million to Morales. A grand jury cleared Officer Karl B. Schultz and a partner at the time, Jason R. Whitenight, agreeing they fired in self-defense as the teenager backed the van he was driving toward Whitenight at the tail-end of a high-speed chase.

Officers Ronald (Ronnie) J. Ammerman , Daniel Derenda
Description

Tremel Stone was shot while his back was facing Officer Ron Ammerman and he was running away. Stone stated that the only reason he ran was because the two officers are well known for planting evidence. Wendy Collier and Ron Ammerman did plant a gun on Stone that was used to charge him with possession of weapon

Outcome

With discovery that was provided during a civil suit, it became clear that the officers conspired to plant evidence on Stone. A civil suit against the City of Buffalo and officers involved for damages was settled for $150,000.

An expert affidavit was submitted by Dannie Sherman, a former law enforcement officer and lead investigator in more than 800 cases. His opinion, with a reasonable degree of certainty, was that the shooting was not justified; there was a cover up with planted evidence with an overall lax review, and the planted evidence was tolerated by the Buffalo Police Department. He states that the level of complaints against Ammerman and Collier is not at all the norm.
