ELIZABETH CITY, N.C. (AP) Andrew Brown Jr. , a Black man killed by deputies in North Carolina, was shot five times, including in the back of the head, according to an independent autopsy report released Tuesday by his familys attorneys.

Also Tuesday, the FBI announced a federal civil rights investigation into last weeks shooting of Brown by deputies serving drug-related search and arrest warrants. The developments come amid increasing calls for the release of body camera footage, including formal petitions to make the video public that will be considered by a judge on Wednesday.

The autopsy was performed Sunday by a pathologist hired by Browns family. The exam noted four wounds to the right arm and one to the head. The states autopsy has not been released yet.

The familys lawyers also released a copy of the death certificate, which lists the cause of death as a penetrating gunshot wound of the head. The certificate, signed by a paramedic services instructor who serves as a local medical examiner, describes the death as a homicide.

Brown was shot last Wednesday by deputies serving drug-related search and arrest warrants at his house in the North Carolina town of Elizabeth City, about 160 miles northeast of Raleigh.

The autopsy results come a day after Browns relatives were shown a 20-second clip of footage from one deputys body camera. Another family lawyer, Chantel Cherry-Lassiter, who viewed the video, said Monday that officers opened fire on Brown while he had his hands on the steering wheel of a car. She said the video showed Brown trying to drive away but posing no threat to officers.

Browns son Khalil Ferebee questioned why deputies opened fire.

Yesterday I said he was executed. This autopsy report shows me that was correct, he said Tuesday at a news conference. Its obvious he was trying to get away. Its obvious. And theyre going to shoot him in the back of the head?
