It could be several weeks before the State Medical Examiner’s Office determines the causes of death of Andrew Giroux, 49, and his son Dustin Giroux, 25, the spokesman for the Department of Public Safety said this afternoon.

Steve McCausland said autopsies on both men were completed this afternoon.

“The office plans to conduct additional studies before determining the causes of death,” McCausland said in a press release.

“In addition, State Police detectives will continue to investigate the deaths and are likely to conduct more interviews in order to assist the Medical Examiner’s Office in reaching a conclusion.”

Medical Examiner Kristin Sweeney performed the autopsies. She was not available to comment this afternoon.

Autopsies are under way this morning on the bodies of a father and son from Saco who died Sunday at their hunting camp in the Piscataquis County town of Sangerville.

There is no indication that the deaths of Andrew Giroux, 49, and Dustin Giroux, 25, were the result of foul play.

Officials hope the autopsies, which are being conducted at the state Medical Examiner’s Office in Augusta, will reveal the causes of death. An initial suspicion that the men died from carbon monoxide poisoning turned out to be false.

The autopsies are expected to be concluded early this afternoon.

If today’s autopsies are inconclusive, or if the men died from some toxin in their systems, it could take weeks for officials to determine the causes of death because of the time it takes to conduct blood tests.
