Investigators are asking for the public's help following a fatal hit-and-run accident early Saturday morning.

Wimberly was brought to Lake Wales Regional Medical Center where he was pronounced dead.

Polk County Sheriff's Office Traffic Unit says pieces of a side mirror from a 1998-2009 Dodge 2500 or 3500 pickup truck. The mirror left behind is a tow mirror. The suspect truck continued heading west on Masterpiece Road, toward Scenic Hwy.
