An internal investigation into other officers at the scene is ongoing and it's not clear whether any others will face discipline. A separate investigation by the state's Bureau of Criminal Investigation is ongoing, looking at whether criminal charges are appropriate.
Coy and the other officer had been dispatched on a disturbance call for someone "continuously restarting a gray SUV" and encountered Hill inside a garage. Both had their guns drawn and approached at an angle from opposite sides, according to her interview.
Coy asked Hill to exit the garage and Hill didn't respond verbally but started walking out of the garage.
Hill's left hand was holding a cellphone but his right hand was "concealed behind his leg." Released records state Hill had reportedly dropped his left hand before Coy shot him but it's not clear from Coy's video that happened -- and Columbus police haven't released any other video.
"(The other officer) stated she did not see a weapon. (She) stated Officer Coy observed a firearm and yelled, 'There's a gun in his other hand, there's a gun in his other hand!' (She) heard gunfire at this moment," according to notes from the interview with the other officer. "(She) had nothing further to add and the interview was concluded."
The memo noted there wasn't audio evidence of the encounter because Coy didn't activate his camera. But once Coy's camera was on and he had audio, the report noted Coy was "verbally aroused and issuing orders" while "Hill was lying on the ground with his back to officers and clearly in medical distress."
"Officer Coy rolled Mr. Hill over and immediately reacted with deep distress using profanity as he realized Mr. Hill was unarmed," the report states.
Officers at the scene didn't perform first aid but did "immediately" ask for paramedics. Coy asked the other officer for a support officer, who would typically help an officer "through a critical event," according to the documents.
"Officer Coy was heard on his (body-worn camera) becoming physically ill," the report states. "Officers began securing the scene with crime scene tape and eventually handcuffed Mr. Hill. Medical aid was only first rendered several minutes later."
The report notes that there was a "protracted delay" for paramedics to arrive and "no officers at the scene administered first aid or provided reassurance to Mr. Hill until several minutes later."
Coy arrived on scene about 1:42 a.m. and Hill was shot minutes later, according to the timeline of events in Quinlan's report, and Hill was pronounced dead at 2:25 a.m. at Riverside Hospital.
