The Umatilla County District attorney's office released the victim's name in a weekend shooting in Hermiston on Monday morning.
Heriberto Aparicio Garcia, 34, arrived at Good Shepherd Medical Center at about 4 a.m. Saturday with a single gunshot wound and was pronounced dead by hospital staff.
District Attorney Dan Primus said he will charge 25-year-old Jesus Carrillo Jr. with murder. Carrillo was arrested Sunday.
Court records show Carrillo has arrests going back to at least 2006 and has several convictions, including a felony in 2009 for manufacturing marijuana within 1,000 feet of a school, and felonies in early 2010 of third-degree assault and felon in possession of a firearm. He spent a year in prison on those charges and is serving a two-year probation.
The Hermiston Police Department was the original investigating department into the homicide. The Umatilla/Morrow Major Crime Team was activated in the investigation, which included representatives of the Oregon State Police, Umatilla Police Department, Pendleton Police Department, Morrow County Sheriff's Office, Umatilla County Sheriff's Office and the Umatilla County District Attorney's Office.
"The inter-agency cooperation was great," said acting Hermiston Police Chief Jason Edmiston. "This was a very well-executed operation from the get-go. In these economic times, all agencies have to be able to depend on each other. The expertise and the experience of the Oregon State Police was outstanding.
"We also had a district attorney who spent the entire weekend involved in the investigation. That speaks volumes about the kind of guy we have in that position."
Edmiston also said, "Nothing about the incident itself is gang-related."
It is the second killing in Umatilla County this year. An Irrigon man, Mario Calvillo Ramirez, was fatally beaten in Umatilla on Oct. 18. A Umatilla teen, Theodore Mendoza, has been charged with manslaughter in the case.
