Drunken driving charges have been dropped against a Warren County man involved in a Saturday morning wreck on U.S. 61 South that left one man dead and sent another to the hospital.

Larry Thompson, 28, 14200 U.S. 61 South, had been charged with DUI and reckless driving after the 1997 Pontiac he was driving hit a 1994 Nissan truck.

District Attorney Gil Martin said Wednesday that blood tests conducted by the Mississippi Crime Lab showed that Thompson wasn’t legally intoxicated. A reading of .10 or higher is considered legally intoxicated. Martin would not release Thompson’s reading.

“The DUI charges have been dropped, but the investigation into possible manslaughter charges will continue,” Martin said.

Thompson was released from the Warren County Jail Tuesday after posting a $2,500 bond.

Mario Lush, 20, Port Gibson, was pronounced dead at the scene at about 2:18 a.m. by Warren County Coroner Ronald Regan.

Thompson was on U.S. 61 South when his car hit the back of the pickup about 10 miles south of Vicksburg.

The driver of the pickup, Nathaniel Williams, 5015 Rollingwood Estates Drive, Vicksburg, was taken to ParkView Regional Medical Center and released after treatment.
