The accident happened at 12:30 a.m. on State Road 407, one mile west of Interstate 95.

The Florida Highway Patrol said 22-year-old Keith Pumphrey of Melbourne, was traveling east on SR-407 and for an unknown reason drove into the westbound lanes and into the direct path of a vehicle driven by 20-year-old Keri DeMott of Orlando.
