A man found on the side of state Route 410 in Sumner Tuesday night had stabbed himself in the abdomen, police said.
Officers responded about 10:30 p.m. to the eastbound lanes between Traffic and Valley avenue exits and found a man in his 20s suffering from a laceration to his stomach.
East Pierce Fire & Rescue firefighters initially reported that he had been stabbed and tossed on the road. It was later determined that the wound was self-inflicted.
He was taken to St. Joseph Hospital in Tacoma for treatment.
