Two 17-year-old boys in Trois-Rivières, Que., have been charged with first-degree murder and conspiracy, a day after the bodies of two sisters and their male friend were found in a home.

CBC News cannot name any of the victims or the suspects due to provisions in the Youth Criminal Justice Act.

The suspects, who were intercepted by police as they were leaving the home Tuesday, appeared in youth court Wednesday.  

Each boy faces three counts of first-degree murder.

According to their lawyer, each teen is also charged with conspiracy to commit murder. They are accused of conspiring to kill a woman, as well as conspiring to kill several police officers.

The two boys made an appearance in a packed courtroom today, attended by some of their family members.

The teens are scheduled to return to court on Feb. 25.

Outpouring of support on Facebook

Police found the bodies of the sisters and their male friend — all in their late teens or early 20s — inside the home on Sicard Street on Tuesday, after receiving a 911 call around 8 a.m. ET.

According to CBC's French service, Radio-Canada, the three appeared to have died from gunshot wounds.

"They were three violent deaths," said Trois-Rivières police Const. Michel Letarte.

Tearful family members were seen being escorted by police outside the home Tuesday.

News of the deaths quickly spread to friends and classmates, and several memorial pages have sprung up on Facebook.

“My sympathies go out to everyone affected by this tragedy, she died too young with her whole life ahead of her,” stated one comment on a memorial page.
