Ottawa Police are investigating an apparent double murder-suicide after a mother and two children were found dead inside their home in Stittsville.

Reports are the children are aged 6 and 10, and that the father arrived home to discover them dead on Monday afternoon.

Tonya Marczak is a neighbor and told 1310news, a 680News affiliate radio station in Ottawa, that her daughter was best friends with the girl who lived there.

“I have no idea what I’m going to tell her,” said Marczak. “How do you tell your five year old that her best friend not able to play with her anymore?”

“What’s the front of the house going to look like tomorrow? Is that yellow tape going to be there? Because that’s not okay,” Marczak said.

The house is located at 25 Granite Ridge Dr.
