St. Tammany Sheriff’s Office detectives are investigating a carjacking that happened Tuesday night near Slidell, according to Capt. George Bonnett.

A woman was sitting outside a Pebble Beach Drive home near Eden Isles waiting for her grandson when she noticed a dark colored vehicle stop nearby, Bonnett said.

A man got out of the dark vehicle, came to the driver’s side window of the woman’s car, pointed a gun at her and demanded that she get out of car. The man, described as African American, weighing about 190 pounds and being between 5-foot-7 and 5-foot-9 tall, then drove off in the woman’s gray Lexus, Bonnett said.

Anyone with any information about the crime is asked to call the St. Tammany Parish Sheriff’s Major Crimes Unit at (985) 726-7847.
