A witness says that a man who died after a three-car accident in Portland had a knife in his chest.

Portland Police have not confirmed the story told to WGME-TV by an eyewitness to the accident, but have said that the man's death is not being considered a traffic fatality. The witness told reporters that the man had a knife in his chest when he staggered from his vehicle after the crash.

According to the Portland Police Department's Facebook page, 22-year-old Patrick Lobor of Portland was the driver of one of three vehicles involved in a traffic accident on Riverside Street, at the intersection with Brighton Avenue. Two people who were passengers in one of the other vehicles were taken to the hospital with minor injuries after the accident that happened just after 1:30 Saturday afternoon.

Lobor was a former basketball player for Deering High School. Coincidentally, Lobor's brother also died on Brighton Avenue, when he was shot and killed in an apartment four years ago.
