In April 2025, police received a report of a sexual assault involving a woman who met a man through a dating app. Since then, additional complainants have come forward with similar experiences.
In four separate incidents, women communicated with the suspect through online dating platforms such as Facebook Dating, Bumble and Tinder. They were later invited to the suspect’s home where investigators believe the suspect drugged and sexually assaulted them.
On Tuesday, March 17, 2026, William McMullin was arrested and charged with multiple criminal charges including sexual assault, administering a stupefying substance, assault with a weapon, voyeurism, assault, mischief under $5,000, intimidation, unlawful confinement and criminal harassment.
McMullin is currently being held in remand until his next court date on March 27, 2026.

“These types of assaults are deeply troubling because they involve a calculated breach of trust,” says Staff Sergeant Christa Laforce of the EPS Sexual Assault Section. “Based on the investigation, we believe there may be additional complainants. If you have been affected, you are not alone, and we encourage you to come forward. Police can help connect individuals with supports and resources.”
Anyone who believes they may have been victimized by McMullin is asked to contact the Edmonton Police Service at 780-423-4567 or #377 from a mobile phone.
