VIDEO: Florida Deputies Dance "Thriller" for Terminally Ill Little Boy

A group of Pasco County, Fla., deputies went above and beyond the call of duty, battling zombies and giving a little boy with a terminal illness a day he'll never forget.

Spencer Holt, 7, has spent far too many days in hospital rooms, battling a form of Mitochondrial disease and seizures.

"There's no cure for it, no timeline for how long of what his future holds," his mother Cher told Fox News 13. "We just live day by day."

When Sheriff Chris Nocco invited him to the Pasco County Sheriff's Office, complete with a motorcade, Spencer's family knew it would be a special day, but they had no idea what was in store.

Spencer loves law enforcement. He also loves zombies. Deputies found a way to combine the two.
