A man has been arrested and accused of drugging and raping women he met on several popular dating apps, and Edmonton police believe there may be more survivors out there that they want to talk to.

The Edmonton Police Service (EPS) said it received a sexual assault report in April 2025 involving a woman who met a man through a dating app.

Since then, police said other women have come forward with similar stories.

In four separate incidents, the accused and the complainants matched and began talking on online dating apps such as Facebook Dating, Bumble and Tinder.

The women were later invited to the suspect’s home, where EPS said investigators believe the suspect drugged and sexually assaulted them.

“These types of assaults are deeply troubling because they involve a calculated breach of trust,” said Staff Sgt. Christa Laforce of the EPS sexual assault section.

Based on what police have found out so far, they believe there are more victims.

“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,” Laforce said.

McMullin is currently being held in remand until his next court date on March 27.

A man on LinkedIn with the same name, who appears to be the same person pictured in the EPS news release, has run a child welfare organization for more than two decades in Edmonton.

The organization’s website said it began operating as a child welfare agency in the early 2000s and partnered with children’s services.

The Edmonton Police Service would not confirm McMullin’s career information and deferred to Alberta Children and Family Services, who provided a statement.

“We cannot comment on the specifics of this case since the matter is before the courts. We will work with police and assist with their investigation in any way required,” said a spokesperson for the children’s service ministry.

“The safety and well-being of children or youth is always our number one priority. When we are made aware of concerns, we assess the situation and take the necessary steps to protect them.”

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.
