The Moose Jaw Police Service (MJPS) is asking the public for help locating a man wanted for several offences, including the possession of child pornography.

Officers first executed a search warrant as part of a firearms investigation on Feb. 20, 2025, which led to several firearms charges, according to a release from MJPS.

An arrest warrant was issued after the man failed to attend his scheduled court date.

Police had executed search warrants for electronic devices during the firearms investigation and discovered child pornography, the release said.

A separate investigation was launched by the MJPS’s criminal investigation section with the assistance of the internet child exploitation (ICE) unit.

Additional warrants were executed for Calvin Longworth, 39. who is now facing several child pornography related charges.

Following the ICE investigation, Longworth has been charged with making child pornography, accessing and possessing child pornography, arranging to commit a sexual offence against a child, sexual interference, invitation to sexual touching, and sexual assault.

Police are asking anyone with information on where Longworth may be to contact them or Crime Stoppers.
