Toronto police have released the names of three persons of interest in connection with a hit-and-run in Scarborough that left a 20-month-old baby in serious condition.

The incident occurred at the intersection of Pharmacy Avenue and Ellesmere Road just before 11 a.m.

Police say three people, including the toddler who was in a stroller, were standing on the south curb when they were struck by a car travelling eastbound on Ellesmere as it crossed through the intersection.

“At that point, what we believe is, an occupant of that suspect vehicle exits the vehicle, assesses the scene and then flees on foot southbound on Pharmacy Avenue,” Insp. Mandeep Mann said. The driver also exited the vehicle, but got back in the car and fled the scene southbound on Pharmacy Avenue.

The vehicle is described as a grey Dodge Journey with the license plate number ANXC 265 which likely has extensive damage to its front end. Police say, as a result of the impact, the front license plate became dislodged and was left at the scene.

Paramedics say two female adults, aged 57 and 37, have been taken to a trauma centre with serious injuries while the baby has been taken to a pediatric trauma centre in life-threatening condition. Police say the baby is expected to survive his injuries now.

Police say Cory Munroe, 49, Derek Desousa, 34, and Amanda Rioux, 30, all of Toronto, are all considered persons of interest and are asking the public for help in locating them.

Police have released a photograph of a man they describe as a person of interest who they believe he may have been a passenger in the vehicle that fled the scene. Anyone with information is asked to contact police.

“We will identify who that driver was. We will identify who that occupant was that came out of that vehicle. My message to those individuals, and anyone else who was in that vehicle, is to please take counsel and turn yourselves in,” said Mann.

Mayor John Tory also tweeted about the incident, calling it an “absolute tragedy.”

“I hope police find those responsible and they are held responsible. I fully support an increase in penalties for those involved in collisions with pedestrians and even steeper consequences for those who flee the scene,” read the tweet.

Tory also added the city is working to make roads safer include lowering the speed limit at the intersection where the three pedestrians were struck and enforcing those limits with automatic speed enforcement.
