Detroit police held a press conference on Tuesday to address the fatal shooting of Porter Burks, a 20-year-old schizophrenic Black man who was killed by police as he was having a mental health crisis. Police said they fired 38 shots in three seconds and killed Burks as he was approaching them with a knife, ABC News reports.

Bodycam footage revealed during the press conference shows officers negotiating with Burks, who allegedly possessed an 8-inch blade knife.

“You’re not in any trouble, just drop the knife and we’ll get you some help,” an officer can be heard saying in the video.
