The father of a tourist who police believe was struck by a car in New Orleans' French Quarter and dragged more than six miles across a Mississippi River bridge is appealing for the driver of the vehicle to turn himself in.

Twenty-eight-year-old Joshua Woodruff died in the accident. Police believe he was hit at about 3:15 a.m. on New Year's Day by a black sedan.

At a Friday news conference with New Orleans police, Woodruff's parents, Mark and Caren Woodruff, appealed for witnesses to come forward. Mark Woodruff said anyone driving or riding in the car that hit his son should come forward and clear his conscience.

Woodruff's family and the Crimestoppers organization offered a $10,000 reward in the case.

Woodruff, an Omaha, Nebraska, native, lived in Los Angeles.
