VANCOUVER - A Surrey family is appealing to the public for information on the anniversary of their mother's death.

Sharon Mitchell was 69 years old when she was struck and killed by a vehicle at around 8:45 p.m. last October.

She was travelling in her electric scooter in a marked crosswalk on 68 Avenue at 138 Street.

Mitchell and her dog were en route to get a bite to eat with a friend from her care home.

“She was riding a bit a head of me coming to the crosswalk,” explained her friend, Henry Gillich.

It’s a memory that’s haunted him every day since last year.

“For about two seconds, I could see what was going to happen because you could hear the vehicle accelerating,” said Gillich from the scene of the crash.

Mitchell was hit by a speeding vehicle and was thrown several metres onto the pavement. She later died of her injuries.

Her dog was badly hurt, but survived.

“I lost a good friend and it was needless,” said Gillich through tears.

The driver fled the scene.

“I could hardly believe it,” recalled Gillich as he revisited the crosswalk.

Mitchell’s family renewed their calls for the driver to turn themselves in Tuesday morning during an emotional press conference outside the Surrey RCMP detachment.

"You will never know the pain and suffering your actions have caused our family. You took away our mother, grandmother, great-grandmother, sister, aunt and friend from all of us who loved her," said Daveen Herman, Mitchell's daughter.

"I know you couldn't do the right thing then, but you could still do the right thing now."

Police say they believe people have more information they can share.

“It’s never too late to come forward and explain your side of events,” said Const. Richard Wright of the Surrey RCMP.

“While nothing can take away the grief that this family has suffered over the last year. Witnesses can bring some comfort to the family by assisting us in solving this case,” added Wright.

Police do have a new lead in the case, a suspect vehicle description.

They’re looking for a 1995-97 blue-green hatchback. Possibly a Pontiac Firefly, Suzuki Swift or Geo Metro.

RCMP says even the smallest tip could help bring the driver to justice.

“There’s no reason for it. When two vehicles are stopped, that should tell people that the crosswalk is occupied,” said Gillich.

Staff at Mitchell’s former care home say the city has promised to install a pedestrian controlled light at the crosswalk in the next few months.

The city did not respond to requests to confirm that.

Anyone with information is asked to contact the Surrey RCMP at 604-599-0502 or Crime Stoppers to remain anonymous.
