Another tragedy has struck the family of a young Western University student killed last October by a drunk driver.

Chris Christidis, the father of Andrea Christidis, died suddenly Tuesday in Toronto. There are reports he suffered a heart attack.

Andrea Christidis, 18, had just finished her first month at university when she was struck by a car driven by Jared Dejong, 25, on Oct. 7, 2015. She died in hospital two days later.

Dejong had left The Spoke, an on-campus bar, with friends and was speeding through campus with his father’s car when he struck Christidis, who was walking on a sidewalk.

Dejong pleaded guilty to having more than 80 milligrams of alcohol in 100 millilitres of blood, causing death. He is slated to be sentenced June 16 in the Ontario Court of Justice.

The Christidis family are part of a large, tight-knit Greek community in Toronto. About 3,000 people came to Andrea Christidis’ funeral visitation and 1,000 people attended her funeral performed by the archbishop of the Greek Orthodox Church of Canada.

Chris Christidis was at the emotional sentencing hearing in April that included three hours of ­victim impact statements that spoke of a young woman who was well loved. He sat quietly with his wife, Georgia, his face etched with sadness, in the front row of the courtroom and had a cousin read his heart-breaking tribute to his daughter.

The Toronto cafe owner was on a flight to Greece when his daughter was gravely injured.

“I was on the other side of the world when I found out my baby girl, Andrea, was fighting for her life,” he wrote.

“Destroyed, horrified, scared and paralyzed in grief, I fell to the ground, helpless.”

The statement told of his flying back to be with his family and making the decision to take his youngest daughter off life support and letting her go.

“A piece of me died that night with her,” he wrote.

“I held her hand and I told her that I will love her forever and not to be afraid.”

Christidis wrote of the months of “torturing myself” over her death, how every day was “a struggle” and how when he closed his eyes at night “she comes to me and (says), ‘Why did I have to go away forever.... what did I do wrong, Daddy?’ ”

Christidis spoke of his feelings of failure as a father for letting his daughter leave home to attend school. “How do you explain to someone what a broken heart feels like?” he wrote.

“I try to carry on knowing that there is a sweet angel in heaven watching over us.. . . I love you Andrea and I miss you every day and for the remainder of my life.”

Christidis and surviving daughter Alexiam stood by his wife’s side during the media scrum where they called for harsher sentences for impaired driving.
