Police arrested a Camas man Saturday on suspicion of shooting his brother in the leg and assaulting a woman with a baseball bat after fearing that the two were trying to frame and poison him, according to the Camas Police Department.

Both are expected to survive their injuries.

Police responded to a reported assault at 1:30 p.m. Saturday at 1732 N.W. Sixth Court in Camas, according to the Camas Police Department. A woman said her ex-boyfriend, Justin Matthew Gibson, choked her and struck her in the head with a baseball bat, but she was able to flee to a neighbor’s home for help, the police department said.

The woman, Courtney Spring Duncan-Frias, 40, of Portland, was taken to a hospital, and Gibson, 36, was arrested at the scene, police said.

Investigators discovered evidence of a separate assault at the same home and learned that Gibson beat up and shot his younger brother, Joseph Levi Gibson, on Friday, according to the police department.

That incident had not been reported to the authorities, police said.

Police said that Justin Gibson drove his brother to the hospital and told hospital staff that his brother fell out of a tree.
