Calgary police said Chelsea Davidenas, 29, was last seen on Saturday, Feb. 17, 2024, and was reported missing by her family on Feb. 27, 2024. Police believe Chelsea was killed hours after her disappearance, however, her remains have not yet been located.

Police have received numerous tips and taken several investigative steps in an attempt to locate Chelsea. Based on the totality of the evidence collected, investigators believe that Chelsea was the victim of a homicide.

Investigators allege Chelsea was lured to a residence located in the 5600 block of Rundlehorn Drive N.E., by two men who were known to her. A short time later, it is believed that she was killed inside the same residence.

Although Chelsea’s remains have not yet been located, based on a significant amount of physical and digital evidence that has been collected to date, on Tuesday, April 2, 2024, two men were taken into custody.

Steven Aaron ZWICK, 26, of Airdrie, and Paul Joseph RUSHTON, 52, of Calgary, have each been charged with one count of first-degree murder. 

It is alleged that Chelsea was targeted because of her history as a sex worker. Investigators do not believe that this case is connected to any other missing persons in Calgary.

It is believed that her remains were removed from the residence on Tuesday, Feb. 20, 2024, and transported in a stolen, dark blue, low-profile, 2001 Honda Civic with white rims to a rural, lightly treed area southeast of Chestermere. Anyone with information about this case is asked to contact police by calling 403-266-1234. 

Late in the afternoon on Thursday, April 4, 2024, members of the Calgary Police Service Missing Persons Team located human remains northeast of Carseland, Alta., near Range Road 254 and Highway 901. Investigators worked with The Office of the Chief Medical Examiner, who has now identified the remains as Chelsea.

Update August 24th 2026: According to Global News, a Calgary man has been sentenced to life in prison after pleading guilty to the second-degree murder of 29-year-old Chelsea Davidenas.

Court heard that Steven Zwick and another man had exchanged messages about targeting women and planned to restrain and assault them. Davidenas was lured to a Calgary residence in February 2024, where she struggled to escape. She died during the confrontation.

Zwick later moved Davidenas’ body to a rural area south of Strathmore. Police recovered her remains on April 4, more than six weeks after her death.

The case also involved another woman who was allegedly targeted by the two men. She became suspicious, managed to escape, and eventually contacted people who helped notify the police.

Zwick was later arrested after an undercover police operation. He ultimately pleaded guilty to second-degree murder and received a life sentence, with no possibility of parole for 15 years.

A second man remains charged in connection with the case. The allegations against him have not been proven, and his trial is scheduled to begin in January.
