LINCOLN CITY, Ore. (AP/WVLT) -- Police stormed into a motel room in this seaside town Tuesday evening and captured a Washington state man suspected of killing his grandparents, ending a multistate search and a tense daylong standoff at the motel.
"Everyone's safe. No one's hurt," said Lincoln City Police Chief Keith Kilian.
Police had spent much of the day trying to persuade Michael Boysen to surrender. After breaching the motel room door, they stormed in and captured him.
Kilian said no shots were fired and Boysen offered no resistance.
Kilian said Boysen had suffered from a self-inflicted wound, apparently a cut. He was taken away in an ambulance.
The bodies of Boysen's grandparents were found Saturday in their suburban Seattle home, a day after Boysen was released from prison and was greeted with a welcome home party.
During the siege in this tourist town, police pointed rifles at the motel, fired blasts from a water cannon and used a bullhorn to try to persuade Boysen to give up.
Boysen checked into the motel Monday night under his own name, but the name wasn't recognized until Tuesday morning when a desk clerk saw a television story about the case and called the Lincoln City police, Kilian said.
Boysen, 26, made threats against members of his family and law enforcement while behind bars, Corrections Department spokesman Chad Lewis said Tuesday. But authorities didn't learn of the threats until after the bodies of the grandparents were found and authorities had started looking for Boysen.
"Sources went to our staff at the Monroe Correctional Center and told us he had been threatening to do all this," Lewis said.
The information was passed on to King County deputies, and that's why King County Sheriff John Urquhart called Boysen extremely dangerous at a Monday news conference.
Boysen just finished serving nine months in prison on a burglary conviction, Lewis said. He had no violent infractions in prison -- "nothing extraordinary," Lewis said.
He served a previous sentence between 2006 and February 2011 for four robbery convictions. Those convictions were related to an addiction to narcotic painkillers, Lewis said.
