Calgary, AB,

New information released in double homicide investigation

Following the second anniversary of the unsolved homicide of Don and Roxanne Carlson, police are releasing new leads while friends of the Carlsons renew the reward for information.

Just before 1 p.m. on Saturday, Feb. 15, 2014, the Calgary Fire Department responded to an alleged carbon monoxide complaint at a residence in the 12200 block of Lake Erie Road S.E. Inside the residence two people were found deceased. Carbon monoxide was ruled out as a contributing factor and the CPS Homicide Unit was brought in to investigate. The victims were identified as Don and Roxanne Carlson, however, a cause of death was not, and will not, be released.

On the one-year anniversary of their death, police released a composite sketch of men observed in the area on Friday, Feb. 14 and Saturday, Feb. 15, 2014. These men remain people of interest in the investigation and have yet to be identified.

At the time of the release of the composite sketches, police also released information about a newer silver or grey pickup truck, possibly a Toyota that was believed to be present near the Carlson’s residence prior to their discovery. Since that release, officers have traced the truck back to a rental agency. The truck was rented by a man believed to be using fraudulent B.C. identification and credit cards. At this time it is not yet known what, if any, involvement this man may have had in the homicide, however, police are asking the public for assistance in identifying and locating him. A photo of the man can be found on The City of Calgary Newsroom.

Over the past year, the Homicide Unit has received several tips and continues to follow leads. They have also worked with the Behavioral Science Unit of the RCMP and Forensic Psychologists to aid in developing new investigative avenues.

Friends of the Carlsons have renewed the $25,000 reward for information directly responsible for the arrest and conviction of the party, or parties, responsible for the murder of Don and Roxanne Carlson.

To be eligible for this reward, anyone with information related to the homicide is asked to contact the Homicide Unit directly at or by phone at (403) 428-8877.
