WATCH (May 28, 2019): Staff Sgt. Martin Schiavetta explains why police are investigating a fatal Calgary house fire as a homicide.
However, police are calling this a “domestically motivated homicide and attempted murder.”
“There was a lot of domestic tension within this residence which led to a violent confrontation on Saturday and we are investigating this as a homicide as well as an attempted murder.”
Schiavetta told reporters the entire family lived in the home at the time of the fire, including Heidar. He also confirmed the mother, Leila Dehdari, was not home at the time of the incident.
According to Schiavetta, police had been called to the home once before for a “domestic event” in December 2018, which was “verbal in nature.”
