Police continued to search a Mississauga, Ont., park Sunday, where body parts were recently discovered, while Toronto officers investigated a new report of remains being found in the city’s east end.

It's not known if the cases in Missisauga and east Toronto are connected.

The latest news on Sunday concerns a second apparent discovery of remains in Toronto.

The first occurred Saturday and then, on Sunday, a bag was found near the location where the first discovery was made.

With regard to the Saturday finding, police are waiting to hear from the Ontario coroner's office and Const. Wendy Drummond said she didn't expect the results of the coroner's review on Sunday.

Drummond told CBC News that the bag found Sunday was believed to have remains inside — though it is not clear if they are human.

Meanwhile, the mystery in Mississauga, west of Toronto, continues to deepen.

A right foot was found by hikers in Hewick Meadows Park on Wednesday and police found a severed head a day later.

On Friday, two hands were found in the Credit River, which flows through the park.

Peel Regional Police, which are responsible for the area that includes Mississauga, have yet to confirm the body parts are from one person.

Investigators believe the remains are female because the foot had yellow painted toenails.

Peel Const. George Tudos said Sunday that the ground search was being aided by cadaver dogs and a dive team.

They're hopeful of finding evidence or the remaining body parts, but Tudos admits  the search would take at least a few days to complete.
