Gatineau police probe possible double-murder suicide

Police in Gatineau, Que., say they are investigating the discovery of three bodies as a double-murder suicide, but have not confirmed that theory.

Police say they are waiting on autopsies, which will be conducted in the next few days in Montreal, to help them confirm. They also would not officially release names of the victims.

Neighbours did confirm to CBC News that Denis Lagace and Lucie Johnson-Lagace, both in their 50s, lived in the home at 115 Saguenay St. They also confirmed that Patrick Johnson, Johnson-Lagace's son who was in his 30s, had recently moved into the home.

All three bodies were discovered by a visitor at about 7 p.m. Friday night. Gatineau police also found a gun near the three family members.

The three died violently, Sgt. Mike Lachapelle said Sunday.

Investigators finished their work Saturday morning at the house, which is in the east end of the city north of Ottawa.

Lachapelle said he did not know if the son lived in the brick bungalow with his parents, but neighbours said all three lived together.

The couple each had children from previous marriages.

Flowers left at house

On the weekend, shaken neighbours and others were placing flowers outside the house on the quiet residential street. There was also a photo placed among the assortment of flowers.

Neighbour Angele Fourchene said she was cooking when she heard police and ambulances outside her door.

“I said, ‘Oh my God, it must be serious’ because it’s non-stop, the sirens are just going on and on and on,” she recalled.

Police said their database doesn’t indicate any previous problems at the house.
