Waterloo Regional Police have confirmed they have stopped searching a regional landfill on Erb Street for the remains of Kitchener woman Catherine Todd.

"It's regrettable. It's probably the most exhaustive search in the history of our service." said Waterloo Regional Police Insp. Kevin Thaler. 

"There was some hope that we would be able to give some closure to the Todd family, but the investigation will continue. The case will go before the courts."

The 48-year-old vanished in March and is presumed dead by Waterloo Regional Police. She was last heard from on March 18 and reported missing by an acquaintance three days later.

Homicide investigators continue to look for Todd's remains as well as a loveseat that went missing from her Kitchener apartment.

On average 11 officers a day, as well as workers with the Region of Waterloo, have been combing through the landfill for Todd's remains since March 26. Police say they have sorted through about 11,300 cubic metres of waste.

James Parise, 26, faces a second-degree murder charge in connection with Todd's presumed death.

He is scheduled to appear in court again on May 22.
