A man has been charged with sexual assault, among other criminal offences, in connection to complaints made by women he met on dating apps.

Police received a sexual assault complaint about the man from a woman in April 2025.

Since then, more women have come forward and reported similar experiences, according to a news release from the Edmonton Police Service (EPS).

In four separate incidents, women reported communicating with the man through Facebook Dating, Bumble and Tinder.

They were later invited to his home, where investigators believe they were drugged and sexually assaulted.

On March 17, William McMullin, 56, was arrested and charged with sexual assault, administering a stupefying substance, assault with a weapon, voyeurism, assault, mischief under $5,000, intimidation, unlawful confinement and criminal harassment.

He remains in custody and will appear in court on Friday.

“These types of assaults are deeply troubling because they involve a calculated breach of trust,” EPS Staff Sgt. Christa Laforce said in a news release.

“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 with information about McMullin is asked to contact EPS at 780-423-4567 or #377 from a mobile phone.
