Auburn – An elderly woman shot and killed by her son on Friday was shot by a shotgun, not an AK-47, according to Stephen McCausland, spokesman for the Maine Department of Public Safety.

“We want to clarify that Margaret Peters was not shot with an AK-47,” said McCausland.

Initial reports from police dispatched to the shooting scene Friday morning said that Mrs. Peters, 70, had been shot in the head by an AK-47.

McCausland said police spent Saturday taking an inventory of the home at 1806 Minot Ave. where Margaret Peters lived with her 42-year-old son James Michael Peters.

When police stormed the home early Saturday morning after a 17-hour standoff, they found Peters’ body resting near a window where he and police had exchanged gunfire earlier in the night.

His mother’s body had been left in the driveway near the home’s front door until police were able to remove it once they determined that Peters himself was also dead.

Among the items collected from the home were weapons and “other items relevant to our homicide investigation,” said McCausland.

“I cannot give you a list of the inventory, but I do know that there were weapons taken from the home,” McCausland stated. An AK-47-style assault rifle was among the weapons, he added.

Results from Margaret Peters’ autopsy, which was performed Sunday, were not available Sunday night.

The autopsy for James Michael Peters is scheduled for today. Whether Peters death was self-inflicted or from police gunfire is expected to be determined by the autopsy.

McCausland said that no note was found during the inventory of the crime scene.
