Provincial police say they believe there may be a witness who can help them determine what happened to a missing Orangeville woman.

Police say that based on forensic examinations of 42-year-old Sonia Varas­chin’s residence, and the area where her car was found, they believe she is a “victim of foul play.”

Police say they are hoping the driver of a white van that was in the area where Varaschin’s car was found Monday may be able to help with the investigation.

Ground, air and trail searches of the Orangeville area have failed to find traces of Varaschin.

Her car was found in an alley Monday morning and police say they found what appeared to be blood on the car and at her residence.

Police told a news conference yesterday afternoon that they have no suspects at the moment, but will continue the extensive search for the missing woman.

Varaschin did not show up for work Monday, and her family reported her missing.
