Two Quebec adolescents were charged Wednesday with first-degree murder and conspiracy in the deaths of three people found in a home.

The 17-year-old males were arraigned in Trois-Rivieres, Que.

The victims have been identified as sisters aged 22 and 17 as well as a 17-year-old boy.

Their bodies were found in a house in Trois-Rivieres on Tuesday morning. Local police said they intercepted two youths moments after they had allegedly emerged from a home.

Authorities have said jealousy is being considered a likely factor in the deaths.

"There seemed to be a certain relationship between one of the suspects and one of the victims," said Trois-Rivieres police spokesman Michel Letarte.

The Crown has asked that the accused be tried as adults, which a lawyer for one of the two said would have an impact if they were found guilty.

"In the case of first-degree murder where the accused is an adult, the sentence is generally 25 years," Rene Duval told reporters in Trois-Rivieres on Wednesday.

"There's a provision in the law that says the maximum is 10 years when the accused is 17 or 16."
