A South Salt Lake man has been charged with attempted murder after what police believe was an unprovoked stabbing of a stranger on a TRAX platform.
Michael Nimmo, 50, was charged in 3rd District Court with attempted aggravated murder, possession and use of a dangerous weapon by a restricted person, and two counts of assault by a prisoner — all first degree felonies.
According to charging documents, a woman was on the TRAX platform at 900 South about 4:30 p.m. on Nov. 21 when she was attacked. UTA security cameras showed the victim standing at the ticket vending machine when a man — later identified as Nimmo — removed a knife from his pants pocket, opened it and approached her from behind.
The suspect “wrapped his arms around the female and pulled her into his chest, and then began repeatedly stabbing the female,” documents said.
When officers arrived, they found the victim unresponsive on the ground and her clothing was “saturated in blood.” According to police, she had been stabbed multiple times in her chest and side. After she was taken to a hospital, medical personnel reported the woman had been stabbed 10 to 16 times.
The victim, whose name has not been released, was in critical condition after undergoing surgery. Updates on her condition have not been released.
Nimmo was identified and arrested shortly after the stabbing when he was matched to images obtained from the security video. After he was taken to the police station, Nimmo “became increasingly agitated,” according to police, and he “jumped up out of his seat and tried to tackle the officer in the room with him.” Officers subdued him, but Nimmo “became agitated again” and “tried to kick and bite two officers.”
Nimmo is being held without bail in the Salt Lake County jail.
