Autopsy results confirm 34-year-old Colleen Dwyer was shot once in the head by her estranged husband in Wednesday's murder-suicide.

Police say 39-year-old Russell Dwyer then fatally shot himself outside a home on Flintridge Square.

Calls of the shooting came in around 4:45 p.m. Wednesday.

When 11 News crews arrived on scene both bodies were in the front yard.

Neighbors say they heard two gunshots, Ron Langkencht just happened to be walking nearby.

"There was a body underneath a vehicle and then up on the grass was another body,” Langkencht said.

Police say there has been a history of violence at the house. Neighbors say the victims were an estranged couple.

Another neighbor who doesn't want to be identified says she knew the woman found dead and she says she saw something very disturbing at this house just a couple weeks ago.

"There was a cardboard box, taped up on the garage," she said. On it was a message someone had written implying the woman had cheated.

"We didn't want to get involved," the neighbor said.

Now she wishes she had.

According to court records Colleen filed a restraining order against the owner of the home back in September.

Police say they found two young children, un-harmed, in the home and a handgun weapon in the yard, near the bodies, another piece of evidence that points to a possible murder suicide.

The Dwyers children, an 18-month-old girl and a 4-year-old boy were in the residence when the shooting occurred. The children are now with grandparents.

The woman also had a least one other, older child who was not home at the time of the incident.

A friend of the couple's who wants to remain anonymous is still in shock.

"Knowing Russ and Colleen, I just can't see it, can't picture it.”

He says he served in the army with Russell, they deployed to Iraq together in 2003 and then both retired in 2006. He reflects on their time in the warzone and times back here at home with their families. He says he knew the Dwyers had been having problems.

"Yes they were having problems, but things were working out as far as I understood."

He knew the couple had split up, but had no idea things had gotten so bad.

"I called him on Monday, talked to him Monday on the phone at work, he told me he was going call me back.”

But he never did and now police say it was Russell who shot his wife and himself while their two young children were inside the house.

"It had to have taken a lot for him to get to a point to do something like this," said Russell’s friend.

Police are investigating this case as a possible murder suicide.
