Washington, April 6 (Inditop) A man is suspected to have killed his five children before killing himself at a trailer park in Washington after hearing his wife was leaving him for another man, investigators said Sunday.

“This is our theory of what happened,” Ed Troyer, a Pierce County sheriff’s spokesman, was quoted as saying by the News Tribune.

“We’re still working to lock down everybody’s account of what happened and when,” he said.

Investigators believe the man, identified by a family member as James Harrison, shot his five children, aged 7 to 16, to death early Saturday in their home in the Graham area in the state’s Pierce County.

According to investigators, Harrison was upset after knowing that his wife was leaving him and family for another man.

Each of the children, whose bodies were found in one of three bedrooms or the bathroom, had been shot more than once, Troyer said.

The father’s body was found later Saturday in a still running car in Auburn, about 29 km from Graham.

The man, believed to be a security guard at a casino who had multiple weapons, apparently shot himself to death with a rifle, investigators said.
