Police have identified a man at the center of a murder-suicide investigation involving five family members as 27-year-old Nikolai Lazukin.

An autopsy shows a gunshot to the head killed Lazukin, who was married with three children.

A medical examiner said Thursday it was consistent with a self-inflicted wound, but neither police nor Deputy State Medical Examiner Larry Lewman would officially call the death a suicide.

Lazukin's body was found Tuesday in a car 80 miles south of a burned house in Salem where his wife and children were found dead. Authorities said the wife and two of the children had been shot, and an infant asphyxiated.

Police released no other details of their investigation.
