New Details About Double Murder Suicide Involving Sheriff's Deputy

GIG HARBOR - It began with an argument and ended with three people killed. Tacoma Police now say a dispute between Pierce County Sheriff's Deputy Allen Myron and his in-laws led to the double murder suicide.

Still though, many questions remain unanswered about my Myron shot Monty and Susan Multanen and then turned the gun on himself.

The pain of three lives lost still shows on the face of Myron family friend Mary Broughton.

"It's just a shock. Beautiful family, loving, busy in the community," said Broughton.

Like most everyone else, Mary can't understand why a devoted husband and loving father would kill his in-laws. Even Detective Gretchen Aguirre with the Tacoma Police Department says investigators are struggling to answer that.

"It didn't appear to be a physical fight, just a verbal argument," said Aguirre.

Cops say while Allen Myron was having words with his father-in-law Monty Multanen, he told his 15-year-old daughter and her boyfriend to go to the basement. Detective Aguirre says that's when the shooting happened.

"The father-in-law was shot two times in the driveway of the residence, he died on the scene. He was actually found in the garage," said Aguirre.

Myron also shot his mother-in-law Susan Multanen in the chest, she died later at Harborview. Mary Broughton believes depression over a back injury might have driven Myron to kill.

"You know to where he could hardly cope and he flipped, he went bezerk," said Broughton.

Myron's wife Sara is a chef and runs her own catering business. Broughton says the couple didn't have a history of domestic violence but money was tight.

"With him not working and her trying to get her business started, I'm sure there were some struggles," said Broughton.

Family friends say Sara Myron and her 4 children are in private grieving. Their house still has Police tape around it. Some people have left flowers in the driveway in remembrance of the victims.

Myron's son Joshua posted this message on his Facebook page. "I love you Dad. I miss you and love you. I will see you someday up in heaven."

Cops say they haven't been able to talk with Deputy Myron's 15-year-old daughter about the double murder suicide yet, because, she is too traumatized. This week Gig Harbor High School enacted their crisis team to help students and staff cope with their grief over the violence.
