State Police Sgt. Richter's body cam footage. Warning: This video contains graphic violence. (Updated) Jebrell Conley appeared to fire first as cops boxed him in and tried to arrest him on robbery-shooting charges at a car wash just over the New Haven-West Haven border.Three of those officers — including two city cops — responded by shooting and killing Conley.Those details are included in a preliminary report released by the state Office of the Inspector General on Monday afternoon.The report, and the accompanying body camera and civilian video footage, detail the final seconds of Conley’s life, amid a confrontation with city and state police officers as they tried to serve a warrant.The state released the report and body cam footage just before 5 p.m. Monday, four days after Conley’s death, per the requirements of the state’s police accountability bill. Police Chief Karl Jacobson and Mayor Justin Elicker provided further details during a 5:30 p.m. press conference at city police headquarters at 1 Union Ave.Click here to read the state inspector general’s five-page preliminary report, and click here, here, here, here, and here to watch police and civilian video footage from the incident.The state inspector general’s report states that, on Sept. 19, the city police department’s Violent Crime Task Force learned that Conley, a 36-year-old New Havener, had ​“an outstanding warrant for his arrest on federal Hobbs Act robbery and related firearm charges.” Jacobson said during Monday’s press conference that that warrant was related to a robbery during which Conley shot someone. He said Conley had been indicted by a grand jury on Sept. 17 on those charges. “Conley’s a known member of the Grape Street Crips,” Jacobson said on Monday. He was on federal probation and had ​“an extensive criminal history.”At around 5 p.m., the 11-person task force received information that Conley was driving a black Hyundai Tucson with a New Jersey license plate in the area of Ella T. Grasso Boulevard and Kimberly Avenue.A license plate reader ​“hit” for that Hyundai. It placed the vehicle at the Splash Car Wash at 2 Boston Post Rd. in West Haven, ​“in the bay area where customers use vacuums to clean their cars,” as the report put it.The task force officers found Conley standing outside of his car at the car wash. They tried to ​“block in” his Hyundai with their own vehicles. Jacobson said Conley was standing outside of his car, with the driver’s side door open. No one else was in the vehicle.“Conley spotted the officers and entered the Hyundai Tucson,” the report states. ​“As officers moved in to apprehend Conley, he appeared to fire one round that shattered the Hyundai Tucson’s front driver side window.” Jacobson added that Conley got back in the car after officers ​“converged on him.” As officers ordered him out of the car at gunpoint, Jacobson said, ​“he put his vehicle in reverse and struck a police car which was directly behind him. Conley then reached for a handgun and pointed it at officers. He appeared to fire one round.”Three task force officers then fired at Conley. Those three were State Police Sgt. Colin Richter, New Haven Police Sgt. Francisco Sanchez, and New Haven Police Officer Michael Valente.

Officers then commenced to provide Conley medical aid,” Monday’s report reads. Jacobson said the officers immediately radioed for an ambulance, and performed ​“life-saving measures” on Conley before he was taken to the hospital.He was transported to Yale New Haven Hospital, where he was pronounced dead.“Officers recovered a handgun, with a high capacity magazine, from the area where Conley had fallen from the vehicle,” the report states. ​“Initial inspection of the handgun suggests that it had jammed after firing one round.”On Sept. 20, the Office of the Chief Medical Examiner determine the cause of Conley’s death to be gunshot wounds to the torso and upper right extremity.Jacobson said that Sanchez, who is a 12-year veteran of the NHPD, and Valente, who is a 11-year veteran, are both on paid administrative leave pending the state’s investigation. The city’s police department has also opened its own internal investigation into the incident.“This is a very rare occurrence,” Jacobson said on Monday. He said the last time a New Haven police officer fired his weapon and killed someone was in November 2004.The Office of Inspector General, the Department of Emergency Services and Public Protection, Connecticut State Police Central District Major Crime Squad, the New Haven Police Department, and the New Haven Judicial District State’s Attorney’s Office are conducting the investigation.“Based on the information, the preliminary status report, and the body camera footage, I believe our officers used appropriate force in the situation to protect themselves, their fellow officers, and the public,” Jacobson said. ​“But this is still an ongoing investigation.”He added, ​“the officers put themselves between Conley with a handgun,” which was stolen out of Waterbury and had an extended magazine with a capacity for 26 rounds, ​“and other innocent people in the parking lot. We believe it was very brave what they did and they had to fire to prohibit themselves from being shot or anybody else in the immediate area.”Jacobson also said that an initial report that the Grape Street Crips were calling in out-of-state gang members to try to harm police officers ​“may have only been rhetoric. We don’t have anything to back it up.” And he said he had spoken with Conley’s mom and brother, the latter of whom assured him that no one wanted to harm police.“I am not an expert. I am not a police officer,” Mayor Elicker said on Monday. ​“It appears to me that the officers used appropriate force. It appears to me that Mr. Conley fired first. It appears that the officers’ lives were in danger.”Asked why he and Mayor Elicker said that Conley ​“appeared” to fire the first shot, Jacobson noted that the state is leading the investigation. He then pointed to the video released by the state on Monday. ​“Watch it yourself,” he said. ​“As you watch it, we are not firing shots until you see Sgt. Sanchez standing there, trying to pull him from the car, and a shot is fired and shatters the window … in the director of Sgt. Sanchez. No other officer fires until that happens.”Police Chief Jacobson (right), with Mayor Elicker on Monday: "I believe our officers used appropriate force in the situation to protect themselves, their fellow officers, and the public."
