On Saturday afternoon, paramedics reported finding the bodies of two adults and one child inside an apartment unit at 85 Thorncliffe Park Dr.

That same day, a death on the Don Valley Parkway left the southbound lanes of the highway closed for hours.

On Sunday afternoon, Det. Tam Bui acknowledged that police are looking at what possible connections could exist between the two scenes.

"There is some correlation, but it is very non-tangible at this time, so we are continuing with the legal identification of the remains and of the deceased people and we will proceed once that identification has been made," Bui told reporters on Sunday morning.

The detective said investigators from the traffic services unit are working with the homicide squad.

Bui would not disclose an exact timeline of Saturday's events, but said police learned of the two scenes within a short period of time.

"It was a report that had been made to us that occurred in close proximity, time-wise to the incident that happened on the DVP," he said.

Bui said police will remain at the Thorncliffe Park building for several days. He also said police are speaking with next of kin "to assist us with a difficult identification."

As of Sunday, Bui said investigators are executing a search warrant at the apartment building and on "several vehicles."

A day earlier, Supt. Scott Gilbert had tweeted that there was "very sad news out of Thorncliffe" and that no suspects were being sought "for this horrific crime."

However, when asked about suspects on Sunday, Bui said police are keeping "an open mind" about the case, which he believes is a homicide.

He said police are looking to speak to any witnesses or anyone with information about anything suspicious that may have occurred at the Thorncliffe Park building from Friday night onward.

Bui said autopsies are scheduled to take place on Monday.
