Hamilton police saidthree pedestrians and the driver of a stolen Toyota Priusdied after the vehicle hopped the curb, smashedinto a concrete hydro pole and burst into flames.

Investigatorshave so far not released the identities of the four people killed in the early-morning crash.

Const.Krista-Lee Ernst saidTuesday it would be up to the victims'families to make their identities public.

The crash involves both "investigative and forensic time challenges," she wrote in an email.

"There are elements of this investigation that take time and need to be processed through the Ontario forensic pathology unit and we continue to work with them closely."

Ernst told CBC Hamilton a male stole the vehicle nearBarton and Kenilworth.

Investigators said the male driver was travelling at a "high rate of speed" and headed westboundtoward King Street East around 2 a.m. when he lost control.

On Tuesday, bouquets were taped to a pole at the scene. The building beside a Pizza Pizza near the corner was charred and boarded up.

A window on an upper floor was shattered. Some people walking byTuesday morning stared at the memorial as they passed.

In an email to CBC, aspokesperson for Pizza Pizza said two of the people who were killed were contracted to do maintenance on the restaurant's equipment.

Milton Joiner, who identified himself onSaturday asa cook at the restaurant, said the location had recently been sold and the cleaners were coming in ahead ofnew owners taking it over.

A man came in and briefly introduced himself to the staff, before going back outside to grab some gear, said Joiner.

"He didn't come back inside," the cook recalled."And then one guy came in yelling and he said 'Fire, fire, fire.'"

The man's chin was bloody, according to Joiner, who said heran to the street to find a car in flames and another vehicle smashed up with someone inside.

"The guy didn't have a chance to get out of the car," he said.
