Police say there is still no sign of high school teacher Jeffrey Boucher from Whitby, Ont., who was reported missing on Monday after failing to return from his usual morning run.

Durham Regional Police Sgt. Nancy van Rooy updated the media on Wednesday afternoon about the investigation into the disappearance of Boucher, 52. The sergeant said that police are still working through a number of leads, but investigators do not know what happened to him.

"To date, he has not yet been located and to date we don’t have any conclusive evidence as to his whereabouts," van Rooy said.

Van Rooy said that police are "very confident" that the ground and air searches they have conducted have covered the majority of the areas where he was known to go running.

Police said social media was abuzz with rumours about the missing father of two and teacher at Bowmanville High School.

But van Rooy said there is no reason to investigate anything in regard to theft or missing money or to believe that Boucher is involved with anything criminal. She said it is possible Boucher "stepped away" voluntarily. If that is the case, she urged him to get in touch with police to let them know he is safe.

She also added that there is no "electronic footprint" for the missing man — no hospital attendance or financial activity since he's gone missing.

Boucher is an avid runner who has gone on early morning jogs before work almost every day for 20 years.

His daughter, Bettina Boucher, told CBC News that her family is trying to stay positive, but they are in the dark about what happened to her father.

"We’re just really confused and we don’t know what could have happened," she said Wednesday, during an interview at the front door of the family’s home.
