The young man police arrested for the Sept. 20 stabbing of Jordan Hull now faces an attempted murder charge.
Umatilla County District Attorney Dean Gushwa said he added the Class A felony charge because it seemed Ramon Edward Coronado had tried to kill Hull.
"We believe that shows one intended to end the life of someone," Gushwa said about the stabbing. "What was his intent?"
Attempted murder has a mandatory minimum prison sentence of seven years, six months.
Coronado, 21, also faces three counts of second-degree assault, one count of third-degree assault and one count of menacing. He allegedly stabbed Hull once in the neck and twice in the head.
Hull was taken to Good Shepherd Medical Center and then to Legacy Emanuel Hospital in Portland for evaluation. The hospital released Hull the same day.
Hermiston Police Chief Dan Coulombe has said alcohol was a factor in the altercation between Hull and Coronado. Authorities haven't released any more information about the altercation.
Coronado remains in the Umatilla County Jail in Pendleton on two $75,000 bonds. He will have a trial readiness hearing at 1:15 p.m. Monday.
