Charges have been laid against an 18-year-old man in connection with a Mississauga crash earlier this month that killed a 31-year-old mother and her two-year-old son.

Khushboo Arora and her husband Sanket Dogra, 33, were driving with their son Prakrit Dogra in the area of Burnhamthorpe and Mavis roads on Nov. 1 when they were struck by a vehicle travelling at a high rate of speed.

Arora and Prakrit Dogra were pronounced dead at the scene. Sanket Dogra was taken from the scene in life-threatening condition to a trauma centre, where he remains.

Evan Campbell, of Orillia, was taken into custody on suspicion of impaired driving after the deadly crash. He was also taken to hospital from the scene with serious injuries.

Campbell was formally arrested and charged with two counts of criminal negligence causing death and one count of criminal negligence causing bodily harm on Nov. 27.

“On the original date he (the suspect) was originally arrested but then released unconditionally until they (the investigators) could actually formulate all the correct charges for the incident that took place,” Const. Danny Marttini said.

“The reality is that it’s just a process in regards to the investigation and how fast they’re (investigators) are able to get the information together; the video footage, the witnesses, putting the scene back together and until they’re sure they have all the facts and issues in the correct format that’s when they can move forward and this is the amount of time it has taken this time.”

Campbell is scheduled to appear in court for a bail hearing on Wednesday in Brampton.

Vishal Sarangal, Sanket Dogra’s brother-in-law, said the charges resemble some sort of closure for the family.

“I mean as a family we are relieved to learn that something has been done about it,” he said. “We have been hoping to get this kind of news for a long time and finally it’s here so at least we think that there will be some sort of a justice for the family members we have lost and for Sanket as well when he recovers.”

Investigators are still appealing to witnesses of the crash and are asking anyone with further information to contact police at 905-453-2121, ext. 3710 or Crime Stoppers anonymously at 1-800-222-TIPS (8477).
