The search for the remains of a Stoney Creek woman will continue now that bone fragments discovered in a Stoney Creek field last September have been determined to be animal and not human, say Hamilton Police.

Three mounted units began searching the field with U of T forensic expert Tracy Rogers on Nov. 22, 2012, hoping to find the remains of Shirley Treadwell, 62.

Treadwell, a Stoney Creek woman who had a mental disability, is believed to have died in 2009. Police were alerted to her death in July 2012.

Treadwell's niece and caregiver, Melinda Evans, was charged in September of last year with committing an indignity to a human body and fraud. Evans allegedly disposed of her aunt's body and collected disability cheques.

More than 450 bones were collected from a field near Winona, Ont., during the search last November. A handful of those bones which could not be immediately ruled out as being human were sent for further testing. They have now been determined to be bones from an animal, confirmed Detective.-Sgt. Matt Kavanaugh. 

The search for Treadwell's remains will continue said Kavanaugh.

"We need some more information from the public or family members or the accused," he added.
