Midtown Manhattan shooter was treated for sports-related concussions, mother said in 2022 police call

The man suspected of shooting dead four people midtown Manhattan last month had years earlier threatened to kill himself as he dealt with depression and concussion symptoms, according to a phone call his mother made to police. On the afternoon of Sept. 12, 2022, Shane Tamura was inside a Las Vegas motel room suffering from a mental health crisis and threatening suicide, his mother told a 911 dispatcher. “He’s under doctor’s care for depression, concussion — like sports concussions — chronic migraine and insomnia,” she said.
