A 26-year-old Airdrie man has been charged with first-degree murder by Calgary police, in relation to the disappearance of a Calgary woman in February. Steven Aaron Zwick was charged alongside a Calgary man, 52-year-old Paul Joseph Rushton.

Rushton has also been charged with first-degree murder. Calgary police said the homicide unit laid the charges in relation to the February 2024 disappearance of Chelsea Davidenas.

"It is believed Chelsea was killed hours after her disappearance, however, her remains have not yet been located," police stated in a press release. 

The 29-year-old woman was last seen on Saturday, February 17, and was later reported missing to police on Tuesday, February 27 after her family grew concerned when they were unable to get in touch with her.

"Since then, we have received numerous tips and taken several investigative steps in an attempt to locate Chelsea. Sadly, based on the totality of the evidence collected, investigators believe that foul play was involved and that Chelsea was the victim of a homicide."

It is alleged that in the early hours of February 17, Chelsea was lured to a residence located in the 5600 block of Rundlehorn Drive Northeast, by two men who were known to her. A short time later, it is believed that she was killed inside the same residence."

Police said they believe that she 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.

"Our Missing Persons Team and Homicide Unit investigators have been working tirelessly over the last month in an effort to locate Chelsea," said Staff Sgt. Mark Rahn of the CPS Homicide Unit. "Tragically, this is not the update that we’d hope to make. We are committed to finding answers for Chelsea’s family and will not rest until her remains have been located."

Police added that 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, the two men were taken into custody. Police are continuing to search for Chelsea’s remains and are asking anyone with information to come forward. 

It is believed that her remains were removed from the residence on Monday, February 20 and transported in a stolen, dark blue, low-profile, 2001 Honda Civic with white rims to a rural, lightly treed area southeast of Chestermere. The men will appear in court on Thursday.
