A mum and her three young daughters were killed when a car went through a red light and ploughed into the side of their SUV at high speed.
The blue Infiniti may have been fleeing police when primary school teacher Karolina Ciasullo and daughters Klara, six, Lilianna, four, and Mila, one, were fatally injured.
Dad Michael Ciasullo has been left devastated after losing his wife and three “princesses” just days before Father’s Day.
A witness said a police car was following behind the speeding Infiniti when the Infiniti went through a red light and slammed into the family’s Volkswagen in suburban Toronto, Canada.
Police said an officer spotted the Infiniti shortly before the crash, but the force did not say whether the officer gave chase. A police watchdog has launched an investigation following the horror crash.
Six-year-old Klara died at the scene of Thursday’s crash in the city of Brampton. Her mum and sisters were rushed to hospital in a critical condition, but later died of their injuries.
A 20-year-old man who was driving in the Infinity – and allegedly known to police for driving offences – was fighting for his life in hospital, CTV Toronto reported.
A witness told TV station CP24 that the Infiniti was driving “very fast” through the intersection when it hit the family’s Volkswagen SUV.
She said: “He just smashed the car. My husband went over there and took the kids out.”
She said a police car was following behind that speeding vehicle at the time of the collision.
Mrs Ciasullo’s sister-in-law Connie wrote on Facebook: “Our world was ripped apart. We lost our beloved nieces and sister-in-law.
“My heart aches in ways I cannot describe with words. To our beautiful Klara, Lila, Mila and Karolina, the only solice [sic] I have right now is knowing that you are together.
“I have no words. Please pray for my brother and both Karolina’s and our family to heal from this tragedy.
“My heart is heavy. We appreciate the outpouring of love we have received while we grieve. My brother has asked to respect his privacy at this time.”
A video has since surfaced allegedly showing the same man driving dangerously in the Infiniti and witnesses trying to open a passenger door to stop him just two days before the crash.
Brampton Mayor Patrick Brown shared the video on Twitter, where he wrote: “Community members & police tried to stop the driver. He was having none of it.
“He belongs behind bars for taking 4 innocent lives. This was his driving prior to the accident.
“@PeelPolice & residents did their best. This was a brazen repeat offender with no regard for human life.”
The mayor also said the suspect had a prohibited licence due to several driving offences.
A family friend who set up a GoFundMe page said Mr Ciasullo was devastated over the loss of his wife and children, and thankful after more than £160,000 was raised.
The friend wrote: “I have just gotten off the phone with Michael and we both broke down.
“He thanked me immensely for everybody’s support. I told him we won’t stop.
“He said I’m so glad that I’ll be able to have the most beautiful funeral for Karolina and his princesses.”
Friend Agatha Kwaterska told CityNews: “This is so tragic and it could have all been avoided and a beautiful family is no longer with us.
“There’s no words to describe what happened and the sadness that everyone feels.”
A GoFundMe page has raised more than £160,000 to support Mr Ciasullo, who installs pools for a living, and cover funeral expenses.
