Police stormed a motel room in a Oregon seaside resort and captured a man suspected of killing his grandparents, ending a multi-state search and a tense siege.
"Everyone's safe. No one's hurt," said Lincoln City police chief Keith Kilian.
Police had spent much of yesterday trying to persuade Michael Boysen, from Washington state, to surrender. After breaching the motel room door, they stormed in and captured him.
Mr Kilian said no shots were fired and Boysen offered no resistance. He said Boysen, 26, 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 on 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 Lincoln City, 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 on Monday night under his own name, but the name was not recognised until Tuesday morning when a receptionist saw a television story about the case and called police, Mr Kilian said.
Boysen had made threats against members of his family and law enforcement while behind bars, Corrections Department spokesman Chad Lewis said. But authorities did not learn of the threats until after the bodies of the grandparents were found and authorities had started looking for Boysen.
Boysen had just finished serving nine months in prison for burglary, Mr Lewis said.
He served a previous sentence between 2006 and February 2011 for four robbery convictions related to an addiction to narcotic painkillers, Mr Lewis said.
