Portland police officers and mental health crisis specialists had a four-hour standoff with a man climbing on trains Saturday at the rail yard at 3930 Northwest Yeon Street in the midst of a thunderstorm and hail, police said.

Matthew Joseph Medlin

Just after 1 p.m., officers learned Matthew Joseph Medlin, 32, had jumped into the bed of a dumpster-style rail car and refused to come out, police said. He repeatedly held pieces of metal and rocks as if they were weapons and injected himself with methamphetamine while officers and others attempted to defuse the situation, police said.

Officers knew Medlin from previous incidents where he has been uncooperative and learned on Saturday he had been awake for more than 26 hours, police said. Project Respond, the Multnomah County Crisis Line and the Police Bureau's Crisis Negotiation Team assisted. Medlin was taken into custody after the Special Emergency Reaction Team fired "less-lethal munitions" and a Taser while he was holding make-shift weapons, police said.

After he was treated at a hospital, Medlin was booked into a Multnomah County Jail on charges of criminal mischief, resisting arrest, criminal trespass, interfering with an officer and disorderly conduct. He also had an unrelated parole violation, police said.
