Calgary police are looking to speak with a man who is believed to have information on a fatal hit and run last week involving a stolen truck that hit another vehicle head-on near the Tsuut'ina reserve. 

The driver of a stolen truck is still at large and police believe Derek Brian Grouette, 33, may have information that could help the investigation.

Two people were arrested near the scene after fleeing on foot, including the underage son of a Calgary police officer and 26-year-old Janelle Umpherville.

Umpherville was charged with possession of stolen property, occupying a stolen motor vehicle and breaching a recognizance order.

She booked a court date of April 18 to plead guilty to her charges.

Around 6:30 a.m. Thursday, an officer with Tsuut'ina police tried to stop a suspicious pickup truck that was speeding on the nation's land west of Calgary but the truck got away.

The stolen truck and a smaller car collided head-on on 37th Street between 130th Avenue and 146th Avenue S.W., killing 52-year-old Keith Morley who was driving the car.

The Alberta Serious Incident Response Team (ASIRT) is also investigating the incident.
