Grieving family members of an off-duty York Region police officer who was killed in a weekend crash spoke about their pride in the life and legacy of Davis Ahlowalia on Monday.

The 28-year-old constable was killed after a minivan crossed the centre line on Major Mackenzie Drive near Pine Valley Drive in Vaughan, Ont. and struck his car at about 3:30 a.m. Saturday.

Ahlowalia's parents Anna and Rishi were surrounded by friends and family on Monday as they tried to come to grips with the loss of their son.

Inside the home were several photos which documented the humanitarian work their son had done in places around the world.

Ahlowalia often spent vacation days in Jamaica and India helping poverty-stricken families. He was planning to travel to South America this year to help orphans and people with HIV/AIDS.

"Amongst his role models were Mother Theresa, John Paul II, and our mother," Davis' brother Anil said Monday.

Visitation for Const. Ahlowalia will take place on Thursday at the Chapel Ridge Funeral Home in Markham, Ont. His funeral is scheduled for 11 a.m. on Friday at St. Mary Immaculate Church in Richmond Hill, Ont.

"We wish to invite everyone who knew Davis to attend his funeral," Anil said. "So we can celebrate the life of my little brother, a true hero."

The horrific accident sent Mohammed Mattu, 19, to Sunnybrook Hospital. He is reportedly in critical condition and on life support.

Mattu and two others were travelling in the minivan at the time.

The two other occupants of the minivan died instantly in the crash. Sulman Yusaf, 19, and Waleed Shaukat, 18, were identified as the victims.
