CALGARY — Police say a six-year-old boy and his mother found dead in Calgary condominium died in a murder-suicide.
Autopsies show Yu-Mei Lai, 39, and her son, Kevin Liu, both died from carbon monoxide poisoning.
Their bodies were discovered about 9:45 p.m. Thursday in a condominium in the city's northwest.
Police have released few details, but confirmed a suicide note was found in the home.
Insp. Paul Stacey said police had no prior dealings with the family and detectives will be looking into whether Lai had any history of mental illness.
Liu, who would have turned seven next month, is Calgary's 14th homicide of the year.
Fire crews arriving to the home in the neighbourhood of McLaurin Village determined there were high levels of carbon monoxide, but it was too late to save the mother and son.
Sherri Raymond, principal at Captain John Palliser school where Kevin attended, wrote to parents offering condolences.
"It is with great sadness and a heavy heart that I write to you today. Some of you may or may not be aware of a serious incident that occurred away from Captain John Palliser School on Thursday, where a Grade 2 student and his mother passed away suddenly and unexpectedly," Raymond wrote.
"Our thoughts are with the student's family and with all of our school community."
Calgary Board of Education spokeswoman Cathy Ward said grief counsellors were sent to the school to support staff and students.
