Last Friday Robert and Norma Taylor picked up their 26-year-old grandson from prison near Seattle and threw a party in his honor. Michael Boysen, however, repaid their kindness by murdering them both after guests left, police say.
The corpses of the Taylors, both in their 80s, were discovered Saturday. Police have not disclosed the cause of death, though they did acknowledge the couple was not shot.
Neighbors told KOMO News they were shocked by the slaying of the elderly Mormon couple. "He was a very, very high level respected man—kindest, softest, gentlest man," one neighbor said of Mr. Taylor.
The Seattle Post-Intelligencer reports that, according to police, Boysen "recently did internet searches for gun shows across the Pacific Northwest and Nevada."
Police believe that Boysen may be driving his grandparents' car.
"We have no idea where he is," admitted Cindi West, a spokesman for the King County Sheriff's Office on Sunday, Kirkland Patch reports.
King County Sheriff John Urquhart said at a Monday press conference, "We want to make sure nobody sells him a weapon." A nationwide alert was issued for Boysen's arrest.
"I can't stress how dangerous this guy is," Urquhart said. "We have to catch him as soon as we can."
