Latest: Police release new details, timeline on Baton Rouge officer-involved fatal shooting

Original story:

A man shot and killed by a Baton Rouge police officer died of a gunshot wound to the chest, East Baton Rouge Parish Coroner Dr. William “Beau” Clark said on Tuesday.

Calvin Toney, 24, died of "a single gunshot wound to the chest with a trajectory of front to back, left to right,” Clark said in a news release.

On Monday night, an officer was making a courtesy escort with a state Department of Children and Family Services caseworker when a struggle ensued between Toney and the officer, State Police spokesman Bryan Lee said. 

The struggle lasted "many minutes" and involved a stun gun, East Baton Rouge District Attorney Hillar Moore III said at the scene. Investigators have already reviewed the body camera footage from the officer, Moore said. 

The officer has not been identified. 

Brandon Jones, a longtime friend of Toney's, said he was in his apartment Monday night when he heard a single gunshot. He came outside, saw a crowd gathering and soon realized that it was his friend who was shot. Toney also lived in the apartment building where the shooting happened, Jones said.

Jones said he tried to take video and get close to his friend, but police kept pushing people back away from the scene. Eventually, he went up to a second story hallway balcony where he took photos of Toney, who had already been shot and was sitting in handcuffs while a female officer tried to treat the gunshot wound.

Law enforcement on Monday night said that Toney was not handcuffed when he was shot by a Baton Rouge police officer and that the incident was captured on a body camera. 

From the balcony, Jones said he talked to his friend to try and reassure him that everything would be okay.

"I was just trying to let him know that someone that he knew that as out her and knew what was going on and that everything was going to be okay, just hang in there. Help is on the way," Jones said he told Toney.
