17-year-old Toni left her cousin's home in Oakland, California on March 16, 1990 to back to her home in San Francisco, California. She was driving her boyfriend's Chevrolet Camaro and had trouble starting it when she left and it kept stalling. The car apparently stalled on the San Francisco Bay Bridge sometime during the evening and another car collided with Toni's car around 12:00am. The police arrived 6 minutes later and found that Toni wasn't in the car after the accident.
Police assumed that the impact of the collision swept Toni into the water below and the Coast Guard dragged the bottom of the bay, but neither Toni or her clothes were located. There was no blood, hair, or oil residue in her car either. Toni's mother says that a week after Toni disappeared, she got a phone call from a young woman whom she believed to be her daughter. The young woman cried on the line for approximately 40 seconds before the call was terminated. The police were unable to trace the source of the call.
Officials believe that Toni drowned the night of the car accident, but her case is classified as a missing person case. Witnesses reported an African-American man looking under Toni's car and others saw the man leaving the scene, but nobody saw Toni's body going over the bridge railing. Toni's bracelet was found on the passenger side floorboard along with her car keys. The man who hit Toni's car was tried for vehicular homicide, but acquitted due to lack of evidence proving that Toni was dead. Toni has not been seen since.
Toni has gaps between her teeth, a mole on her left calf, a scar on her right knee, and pierced ears. She was wearing a black tube top trimmed with lace, black linen shorts, a light blue jacket, white loafers, a gold chain bracelet, and two golden nuggets on her right hand. She was a high school senior in 1990, enjoyed swimming and dancing, and was on her school's track team. Toni was two months pregnant at the time of her disapperance. Her case remains unsolved.
