Olivier's vehicle, a dark green 1998 Isuzu Hombre pickup truck with the Texas license plate number ADG3707, was found abandoned by Everglades National Park rangers in a parking lot beside Pine Glades Lake in Homestead, Florida on August 27, 2011. The rangers noticed it had been parked there for several days. The receipt inside the truck indicated Olivier went to the park on August 24, and a surveillance video showed him driving in alone at 1:00 p.m. on that date. The last time his cellular phone pinged off a tower was at 4:45 p.m. Olivier had no known friends or relatives in Florida and his family didn't know he was there until his truck was found. He has never been heard from again. Olivier lived in Texas at the time of his disappearance. It's uncharacteristic of him to go this long without getting in touch with his relatives. The circumstances of his disappearance are unclear. He has black hair and green eyes. Olivier's hair was styled in a Mohawk at the time of his disappearance. His ears are double-pierced. His nickname is Jake.
