A 27-year-old Milton man killed in a devastating five-vehicle crash on Highway 401 in Mississauga that sent 14 people to hospital, has been identified as Amjad Hussain.

Friends and family members of the young man have taken to social media to express their condolences.

“A young brother, a good friend, an excellent person and a helping hand for his family,” wrote Mehdi Hassan in a Facebook post.

Another friend took to Twitter to say that Hussain was “a great guy” who loved to travel.

OPP Sgt. Kerry Schmidt said children were among those injured in the collision, which occurred around 5:30 p.m. in the eastbound lanes of Highway 401 near Winston Churchill Boulevard.

A passenger in Hussain’s vehicle, who one friend described as a family member, was seriously injured. The other injuries, including the children’s, were described as minor, although all 14 people hurt were hospitalized.

Schmidt said speed was not believed to be a factor in the collision. He said it appears as though all five vehicles were in the passing lane when a sequence of rear-end collisions occurred.

“You can still see some of the marks on the guardrail,” Schmidt said in a Twitter post.

Schmidt said investigators are on scene “mapping” the evidence and will be re-constructing the crash in an effort to determine how it occurred.

No charges have been laid, but Schmidt said the investigation is ongoing.
