Ware County Sheriff Randy Royal says 45-year-old Michael Southerlan Carter struck his son's truck with his own pickup truck, running the son, 20-year-old Thomas Matthew Carter, off the road.
Royal says the elder Carter was charged on Monday with aggravated assault and felony murder in his son's death on April 5. He's being held at the Ware County Jail.
Officers say the father did not realize his son's truck contained a passenger, who was only slightly injured.
The passenger later told investigators that Michael Carter drove his truck into his son's truck several times, finally causing it to overturn.
