The Sureté du Quebec is investigating what appears to be a double murder-suicide at a nudist campground near Drummondville.

Three bodies were discovered Monday afternoon at the Adam & Eve campground in Sainte Brigitte des Saults, but it's possible the three people died several days earlier.

The victims have been identified as Suzanne Gareau, 50, Rodrigue Tremblay, 77, and Denys Carpentier, 76.

Those who knew the three at the nudist camp believe the police hypothesis that the tragedy is a result of a love triangle. They say Carpentier and Gareau were in a romantic relationship, and when they recently broke up, she moved in with Tremblay.

They say Carpentier grew very jealous and was angered by the split.

Others said they were taken aback by the crime, adding that before the split all three were well known as good natured and friendly people.

Autopsies will be performed to determine exactly how all three were killed, but police believe Carpentier killed the other two before taking his own life.

Police later confirmed that all three people had been shot, and that the bodies were all found in the same cottage at the campground.

Despite the close proximity of neighbouring homes, people who talked to CTV never heard any shots and could not say when exactly the murders took place.

"I never heard anything, but I do know that it was two days since we had seen Tremblay," said one man.

On Facebook, Tremblay's granddaughter Audrey wrote a message about the death.

"This event is sad for each of us. I thank you for your thoughts and support. I wish for a world without hate, jealousy and spitefulness," she wrote.

There was another fatal shooting at the same campground in 2010.
