Police are probing an apparent double homicide involving a Montreal-area doctor while autopsies are conducted on his two young children, who were found dead in their home in the small Quebec community of Piedmont on the weekend.

Three-year-old Anne-Sophie Turcotte and five-year-old Olivier Turcotte were found Saturday morning by police who had been asked to check on the home by concerned relatives.

They also found the children's father at the house, alive and in need of medical attention due to an apparent drug overdose, police said.  

The 36-year-old cardiologist, whose name has not been confirmed, is a possible suspect in what police said appears to be a double slaying and attempted suicide.

When he was taken to the St-Jerome health and social service centre in the Laurentians for treatment, doctors there realized he was one of their colleagues.

Hospital director François Therrien confirmed the man was having marital problems. He and his wife, who is also a doctor at the hospital, have worked there for about six years.

The man has since been transferred to hospital in Montreal. Police said they will question him as soon as his doctors approve.

The autopsies on the two children were expected to be done Monday or Tuesday in Montreal to determine the cause of death.
