A Portland man accused of pointing a gun at someone in Keizer was arrested Wednesday after police say he ran from officers chasing him and was later spotted on a log floating down the Willamette River.

Water rescue teams from the Salem Fire Department and Oregon State Police had to fish Robert Tudorache, 33, out of the river about four miles downstream from a boat ramp where police believe he entered the water, according to the Keizer Police Department. He was then taken to a hospital.

Police said Tudorache will be booked into the Marion County Jail after he is released from the hospital on suspicion of unlawful use of a weapon and menacing.

Someone called 911 around 4:45 p.m. and reported a man with a black garbage bag covering the top half of his body was in Keizer Rapids Park threatening to kill and pointing a handgun at another person, police said.

Officers later arrived and found the man, who police later identified as Tudorache, on a park walking path. He ran into the woods.

A resident in the area told officers around 5:35 p.m. that he’d seen a man on a log floating downriver, police said. Officers found Tudorache clinging to the log and floating in the river a little before 7 p.m.

Police haven’t provided more information about Tudorache’s condition after he was pulled out of the water.
