Antionette Jean Whitaker was 13 and living in a foster home when she disappeared from Seattle on the evening of July 9, 1977. Witnesses say she was last seen walking away from the foster home with an unidentified man. Her body was found a week later, on July 16, 1977, in a vacant lot in the Lake City neighborhood; she was fully clothed and positioned on her hands and knees. An autopsy determined she had been stabbed to death and found no evidence of sexual assault.

The case remained unsolved for decades. Police later identified Rodney James Alcala as a person of interest in several unsolved Washington murders, including Antionette’s, noting his presence in the Seattle area at the time and that jewelry from two of his California victims was found in a Seattle-area storage locker he had rented in 1979. Alcala was never prosecuted or convicted for Antionette Whitaker’s murder.

Does anyone have memories, records, or information about Antionette’s last known movements, the unknown man she was seen with, or the Lake City lot where she was found?
