The search continues for the grandson of an elderly couple found dead in their Renton home on Saturday.

The King County Sheriff's Office says they received information that Michael Boysen, 26, may be looking to obtain firearms. Boysenis considered to be an extreme danger to the public and police.

Detectives said the credibility of the information was bolstered by Boysen s internet searches just before or after his grandparents' double murder.

Boysen had done an internet search of gun shows across the Pacific Northwest and Nevada.

Boysen is suspected of murdering his grandparents in their Fairwood home sometime late Friday night or Saturday morning.

Friends identified the victims as Robert and Norma Taylor, who were both in their early 80s.

On Sunday, crime scene investigators combed through the Taylor home.

I don t even know what to say, said Julius Tiangson, a neighbor who lives down the street.

Neighbors are stunned.

It s hard to believe this is actually happening in your own neighborhood, said Tiangson.

According to police, the couple s daughter last heard from them around 10 p.m. Friday night.

Another family member became concerned when the Taylors didn t answer the door Saturday and called their daughter. She went to check on them around 7 p.m. Saturday and found their bodies.

We have issues with theft and things like that but nothing to this degree, said Doug Kinzig, a neighbor.

Police say there were no signs someone forced their way into the home.

It s unusual something like that had occurred without a break in, said Melvin Char, a neighbor.

A 2001 Red Chrysler 300 is missing from the couple s home. It has the Washington License Plate 046 XXU.

Boysen had recently been released from prison after serving a year for burglary.

Somebody wasn t happy there, sounds like the grandchild, but you don t know, said Kinzig.

Family members were at the home Sunday trying to make sense of the senseless crime.

I hope they do find whoever is responsible, said Tiangson.

Boysen is 5-foot-10 and 170 pounds. Police are asking anyone who sees Boysen or the missing vehicleto immediately call 911.
