The incident occurred on November 22, 2013, when members of the Medicine Hat Police
Service responded to an alleged domestic abduction.
Officers identified a vehicle believed to be associated with the abduction
and attempted to stop it. However, the vehicle fled and police pursued it out of
the city and west of Medicine Hat on Highway 1.
When the vehicle left the jurisdiction of Medicine Hat, RCMP officers took
over the pursuit which reached speeds up to 177-km/h.
The suspect vehicle turned onto Highway 884 and then veered suddenly into the
path of an oncoming tractor-trailer unit.
The collision killed the driver of the suspect vehicle, identified as 27-yer
old Branden Anderson and his passenger, 33-yer old Crystal Trotchie.
The driver of the tractor-trailer was treated for minor injuries.
The Alberta Serious Incident Response Team, or ASIRT, noted that police
searched a home in Medicine Hat, where the suspected abduction had occurred, and
found evidence the woman was taken against her will.
It was the responsibility of ASIRT to investigate whether officers involved
in the incident had caused the death of the two people in the suspect vehicle or
committed any criminal offences.
ASIRT Executive Director, Clif Purvis, reviewed the team's investigation
and determined that none of the officers from either Police agency had caused
the deaths in this case.
