From the club:

Williams, who served as a Panthers scout for the last eight seasons, was involved in a fatal car accident late last night. He is survived by his wife Lucy and three children Sandy, Jeff and John.

"Luke was a true professional and an exceptional human being," said Florida Panthers General Manager Dale Tallon. "The thoughts and prayers of the entire Panthers organization and our fans are with his family during this difficult time."
