The serial killer continued to California. On April 4, 1984, he picked up Tina Marie Riscio, a 16-year-old girl, at a dress shop in Torrance, California. For the next three days he held her hostage, torturing her with a 110-volt prod. Under the penalty of death, Wilder made the girl his unwitting accomplice. Together they drove eastward just as the FBI added Wilder’s name to its Ten Most Wanted list.
