The Orange County coroner identified two of three people found dead early this month at an Irvine home, the scene of a possible murder-suicide.

Karina Poirier, 55, and Serge Poirier, 63, were found with another adult April 6 at a home at 58 Riverboat by Irvine police. Their bodies were “severely decomposed,” police said at the time.

The deceased were believed to be a mother, father and son, authorities said.

Detectives believe the third person is Morgan Poirier, 21, the Irvine Police Department said Friday in a release, adding that coroner’s officials were using DNA to make a positive identification.


L.A.’s city attorney filed charges against funeral director Mark B. Allen, who faces up to 11 years in jail for improperly caring for human remains.

All three people sustained a gunshot wound, and a gun was found at the scene, police said in the release.

Irvine officers had responded to the home for a welfare check on behalf of Canadian authorities after extended family members said they had not heard from relatives for over a year, police officials said this month.

Officers did not find any signs of forced entry and said it appeared to be a domestic incident that ended in a murder-suicide.
