SANGERVILLE (AP) — Maine authorities are planning autopsies to seek the causes of death of a father and son from Saco who were found dead in a hunting camp in Sangerville.

Steve McCausland, a spokesman for the Maine Department of Public Safety, said detectives listed the deaths as “unexplained.”

The two were identified as 49-year-old Andrew Giroux and his 25-year-old Dustin Giroux.

McCausland said the two men were spending the weekend at the camp with four others. The elder Giroux was found dead outside the camp Sunday morning. His son was found dead inside in bed.

Police have interviewed the four other men. Authorities said there was no obvious sign of foul play.

The autopsies are scheduled for Tuesday.
