PORTLAND, Ore. (KOIN) — A Portland man suspected of stabbing and killing his father has been arrested, Portland Police said.

Officers arrested Tyler Wayne Nees, 30, on Thursday at Northwest 23rd Avenue and Lovejoy, 12 days after his father, 64-year-old Brian Nees, died.

Tyler was found in possession of a realistic-looking replica firearm. He’s being charged on murder, unlawful use of a weapon, a parole violation and possession of meth.

Police said the stabbing happened on Dec. 2 near Southeast 72nd Avenue and Woodstock at around 1:55 a.m. Police said Brian went to Mt. Scott Pub after he was stabbed. Employees were cleaning up at the time, but they saw Brian and gave him towels while they called 911. He died after 5 p.m.

Later that day, at around 3 p.m., police set up a perimeter between Southwest 3rd and 5th and Southwest Columbia and Jefferson because someone matching Tyler’s description ran from police. They even checked a local business looking for him, but they couldn’t locate him.

“Anytime you have a homicide suspect in the community we have concerns,” Portland Police Sgt. Pete Simpson. “We don’t know what the person will do if confronted.”

Police said an anonymous tip to Crime Stoppers led to the arrest.
