The 42-year-old Trenton man not only was expected to survive but to be out of the hospital in short order, Trenton police said.
The unidentified victim, who had been drinking, was stabbed when he got into a fight on his porch about 2 a.m. Sunday, went to sleep without realizing he was wounded and woke up hurting but still unaware of his predicament, police Lt. Mark Kieffer said.
"And his brother said he had a knife blade protruding from his back," Kieffer said.
The victim was "very uncooperative" when investigators tried to interview him at the hospital, Kieffer told the Times of Trenton.
The assailant, who fled during the fight, had not been caught, police said.
