Robert Joseph Simonson, 41, is facing charges of murder, unlawful use of a weapon, interfering with a peace officer, and tampering with evidence, among others.
It happened on the 1500 block of Rogue River Highway around 6:30 a.m. Friday. The victim, Kimberly Ann Staack, 52, was taken to a nearby hospital where she was pronounced dead.
Police say Simonson fired a single shot that ultimately killed her. Police say the two had been living together in various means. Officers say they were transients, sometimes living in camps and with friends.
Investigators say there was arguing prior to the incident between the two. The case is being turned over to the Jackson County District Attorney’s Office next week.
