BATON ROUGE - A former LSU and NFL running back was formally charged on vehicular homicide charges stemming from a Baton Rouge crash that killed two people and sent two others to the hospital in critical condition.

Court records show Richard Murphy was formally charged Thursday on two counts of vehicular homicide and one count of first-degree vehicular negligent injury.

He was allegedly involved in a June 14 wreck along Main Street that killed Robert Tarver, 94, and Carla Tarver, 69. Murphy was allegedly driving a Ford F-250 and crashed into the Tarvers' Ford F-150. Witnesses said the F-250 was driving erratically at a high rate of speed before running a red light and striking the passenger side of the F-150.

Sources told WBRZ that Murphy was allegedly intoxicated at the time of the crash.
