She added: "We want to appeal to the driver involved to please search your conscience and come forward.
"Help us understand the circumstances and allow us to start grieving properly.

Following a post-mortem examination and police inquiries, Fife Police confirmed on Monday July 15 Mr Walker's death was the result of a hit-and-run collision.
