Seven officers were placed on paid administrative leave after a man became unresponsive and died on July 11 following a struggle with police, in which officers were seen on video holding him face down outside a local seafood restaurant in a Boston suburb, officials said. Videoshowed multiple officers attempting to restrain a person, later identified as Francis Gigliotti, 43, by holding him face down on the ground outside Bradford Seafood in Haverhill, a city about 35 miles north of Boston. He became unresponsive and was later transported to a local hospital, where he was pronounced dead, the Essex County District Attorney's Office said in astatement. It was not clear how long officers were restraining Gigliotti or when he became unresponsive. Officers involved in the incident were not wearing body cameras, according to Haverhill Mayor Melinda Barrett, butvideo taken by witnessesshowed Gigliotti crying out for help. The incident occurred after the Haverhill Police Department received a call reporting that a man was "behaving erratically" and running into oncoming traffic in the area, the county district attorney's office said. Gigliotti's fiancée, Michele Rooney, toldlocal television stationsthat he was experiencing a mental health crisis and was not armed. "People that were there before I got there videotaping it said that he was hollering, 'Help, help, get off of me, help me, help me,' and they had their knee on his neck and they were sitting on him. They were like, it was like a giant pig pile on top of him," Rooney said in an interview withWBTS-CD. In astatementon July 14, Barrett said the seven officers involved in the incident were placed on administrative leave as they investigate Gigliotti's death. The county district attorney's office has alsoasked the publicto submit photos and videos of the incident to help with the investigation. "The City of Haverhill mourns the loss of Mr. Gigliotti, a lifelong resident," Barrett said. "Mr. Gigliotti, his friends and family, and the public deserve a thorough and transparent investigation of his death." 'Rise in police violence':US sets another grim record for killings by police in 2024 Haverhill police received a call at around 6:22 p.m. ET on July 11 about a man "behaving erratically," according to the county district attorney's office. The caller reported that the man, later identified as Gigliotti, had fallen on the floor after leaving a building and was running in the middle of the street. Gigliotti also reportedly hit a car with his head before continuing down the street. Surveillance footage captured him moving in and out of traffic, where he was nearly hit by several cars,the county district attorney's office said. "Responding officers arrived on scene and found Gigliotti behaving in an erratic and belligerent manner and called for an ambulance to assess his well-being," according to the county district attorney's office. Before the ambulance arrived at the scene, the county district attorney's office said Gigliotti fled on foot and tried to enter Bradford Seafood. Police attempted to restrain him "for safety reasons" and Gigliotti became unresponsive, according to the county district attorney's office. First responders tried to render medical aid, and Gigliotti was transported to a hospital where he was pronounced dead. Gigliotti's cause of death has not yet been determined, according to the Essex County District Attorney's Office. The medical examiner will conduct a full autopsy to determine the official cause and manner of death. "When I got there and there were 7 or 8 cops on top of him and he's yelling, 'Help me, I can't breathe,'" Rooney said at a July 14 protest over Gigliotti's death,according to CBS News Boston. "It's something that will be etched in my brain forever." Barrett said the county district attorney's office is currently leading the investigation, which includes interviewing all responding officers and civilian witnesses. When is deadly force justified?Recent police killings raise questions During the July 14 protest, family and friends of Giliotti accused officers of mishandling the situation, CBS News Boston reported. Family members said Giliotti — who recently lost his mother and brother, and had been hit by a bus — had struggled with mental health issues, according to the television station. "He needed support and nobody was there to do that for him," Giliotti's niece, Leti Torres, said at the protest, CBS News Boston reported. According to Barrett, the city of Haverhill funds both a behavioral health clinician embedded within the police department and a social worker who works with police on drug intervention. The mayor added that the police department's behavioral response unit responded to over 800 calls in 2024. "As we mourn, we must also reflect on how we help those in crisis," Barrett said. "I am committed to building on these resources and investing in additional training and equipment for the Haverhill Police Department." On July 15, U.S. Rep. Ayanna Pressley, D-Massachusetts, called for a "swift and thorough investigation" into Giliotti's death. Earlier in the day, Pressley had joined Pennsylvania Democrat Rep. Summer Lee in introducing two bills that "take a public health approach to public safety and support individuals in mental health crisis." "Unfortunately, we'll never be able to deliver justice for Francis Gigliotti — for in a just world, Francis would be alive today, at home with his fiancée and family—but we can and must provide accountability and policy change," Pressley said in astatement. "I look forward to seeing a transparent and independent investigation led by District Attorney Tucker so the community writ-large can get the answers and healing they deserve." George Floyd's death:For a moment, George Floyd's murder changed everything. Those days are gone. Law enforcement experts have widely discredited the technique of handcuffing or holding someone face down, as it can cause suffocation if a person is held down too long or excessive pressure is applied. "When someone is restrained in such a way that their belly is to the ground, it's called prone restraint," according to theDisability Law Center of Virginia. "Positional asphyxiation is when the positioning of someone's body prevents them from breathing adequately, and this form of asphyxia is the reason that prone restraint sometimes results in death." In a 1995guidance on the use of forcefrom the Department of Justice, the department stated that "unexplained in-custody deaths are caused more often than is generally known by a little-known phenomenon called positional asphyxia." "As soon as the suspect is handcuffed, get him off his stomach," the Justice Department further advised. The report also noted that a suspect may appear to be resisting if the airway is blocked: "The natural reaction to oxygen deficiency occurs — the person struggles more violently." Several extreme cases of prone restraint have reignitedcalls for police reformand demands for systemic change in recent years, including the2020 murderofGeorge Floyd, an unarmed Black man who died after a former Minneapolis police officer knelt on his neck and back for more than nine minutes. Experts whopreviously spoke with USA TODAYcalled the officer's actions excessive and dangerous. "When somebody says, 'I can't breathe,' that is a medical emergency and you get EMS to treat them right way," John Peters Jr., president of the Institute for the Prevention and Management of In-Custody Deaths, told USA TODAY. "Because at that point, the suspect becomes a patient." How much has changed?After George Floyd's death, many declared racism a public health crisis.
