Driver who fled had drugs in car and house, Dorchester County Sheriff’s Office says

Authorities are looking for Antuan Dante Prioleau, 34. of Crestview Drive in Summeville after a chase and crash on Ladson Road Tuesday.

The driver who led deputies on a chase before crashing on Ladson Road Tuesday afternoon had cocaine in his car and more drugs in his house, according to the Dorchester County Sheriff’s Office.

Authorities are looking for Antuan Dante Prioleau, 34, of Crestwood Drive in Summerville, Chief Deputy Sam Richardson said.

Prioleau failed to pull over for a traffic stop at Trolley Road and Midland Parkway and led deputies on high-speed chase, Richardson said.

Prioleau passed several cars in the median and crashed his Chrysler 300 head-on into a pickup truck about 3 p.m. at Ladson Road and Palmetto Commerce Parkway, according to the Highway Patrol.

Prioleau ran into some woods. The pickup driver, a 44-year-old Summerville man, was taken to Summerville Medical Center by ambulance.

Multiple agenices set up a perimeter around the woods but didn’t find Prioleau.

Deputies found a white powder presumed to be cocaine in Prioleau’s car, Richardson said. When they searched his house with a warrant, they found 866 grams of heroin, 578 grams of cocaine, 34 grams of marijuana and $8,000 in cash, he said.

Prioleau’s girlfriend, Sonobia Amelia Grayer, 25, was arrested at the house on narcotics charges, Richardson said.

Prioleau is not considered armed or dangerous, Richardson said.

Anyone with information is asked to call the sheriff’s office at 873-5111 or leave an anonymous tip with Crime Stoppers at 554-1111.
