COLLINGWOOD — The ongoing investigation into the murders of two Blue Mountains residents moved into town, Thursday.

On Thursday morning, members of the OPP's underwater search and recovery team were combing through the muck of Black Ash Creek just above the bridge on Balsam Street, as the search continued for clues to the deaths of Michael and Kathryn Rogers.

The couple were found in their Kitzbuhl Crescent home on June 6, as police followed up a missing person call after Michael Rogers' employer reported his disappearance.

Michael Rogers was the manager of homeowner services at Blue Mountain Resort, a position he held for two-and-a-half years.

The couple has been described as quiet and caring.

OPP spokesperson Sgt. Peter Leon confirmed in an email that the search of the creek — and of the stormwater management pond at Mair Mills on Mountain Road on Friday — is part of the continuation of the investigation.

The unit went through several watercourses nearby the murdered couple's home in the days following the discovery of their bodies.

Police have not indicated how the couple died, other than to confirm it was a double-homicide.

Otherwise, police have been tightlipped about the investigation.

Two days after the murders were discovered, Rogers' brother Adam was killed in a head-on collision with a tractor trailer on Hwy. 26, between Barrie and Stayner.
