Seven years after the death of her son, Carol de Delley still fights for a cause that has created financial hardship.

Tim McLean was killed on a Greyhound bus in 2008 by Vince Li.

After Li was found not criminally responsible for the act, de Delley fought to keep him off the streets.

Her fight took considerable time and money.

De Delley said she missed out on income and career growth, and incurred more debt.

“We’ve survived everything else but at the end of the day, we have nothing for our retirement. We have nothing for our future. If my husband lost his job tomorrow, I don’t know where we’d be next month,” said she said.

She found work at night as a house cleaner, but soon has to stop to care for her grandkids, including a child left behind by her late son.

“Five months after Timothy was murdered, a grandchild was born. And we are positive that this is Timothy’s child,” said de Delley.

After seven years of struggles, de Delley’s family wanted to help.

A GoFundMe page was set up for Carol and her husband, to help offset costs associated with McLean’s death.

“We just thought it was a great way to help them try and recoup some of the dollars that they haven’t earned or have expended on other things which pertain to this event,” said McLean’s great-uncle Dave Melcosky.

Melcosky hopes sharing de Delley’s story will show Canadians the financial cost of a terrible crime.
