A mother from Canada who lost her three children in a drunk driving crash just posted a truly heartbreaking photo on social media showing their lunchboxes on their graves on what would have been their first day of school.

Jennifer Neville-Lake of Ontario shared the photo of the lunchboxes with one balloon tied to each one. These were the last lunchboxes she bought for her children, Daniel, 9, Harry, 5, and Milly, 2, before their tragic deaths in 2015.

“Grade 8. Grade 4. Grade 2. Or rather, should be! These were their lunch bags for their 2015 school year,” Neville-Lake began her Facebook post. “Our family’s first day of school because of a drunk driver.”

Constable Andy Pattenden with York Regional Police explained that the three children were driving with their grandparents in Vaughan, Ontario, on Sept. 27, 2015, when the car was struck by a drunk driver.

“It was a t-bone collision at an intersection,” Pattenden said. “The impaired driver failed to stop at the stop sign.”

Pattenden said that the driver was arrested and charged with various drunk driving offenses, and that the person is currently in prison. Neville-Lake said that Daniel died the same day as the crash took place, while Milly and Harry died the next day after being taken to the hospital.

“I hate my life now because of what the drunk driver did to my family,” the grieving mom said. “I hope that by sharing my reality people will make better choices. Maybe seeing or reading my pain will help someone else make a better choice.”

Neville-Lake’s father Gary Neville also died in the crash, with her mother Neriza Neville, and the kids’ great-grandmother, Josefina Frias, being the only survivors. Though it’s been four years since their deaths, Neville-Lake vividly remembers the moment she was told her children were gone.

“I remember saying to the doctor, ‘All of my children? All of my children are gone? This can’t be true,’ ” she recalled. “Our lives are pretty much over because our whole family has been taken.”

“No mom should have to hold all her children’s death certificates in her hand instead of getting hugs and kisses from them on her 40th birthday,” she added.

After the deaths of her children, Neville-Lake founded the Many Hands, Doing Good non-profit to support children who have experienced trauma through the arts.
