Circumstances of Disappearance

Sylvia Lourdes Standley (sometimes incorrectly reported as Standly), with the possible alias last name of Baca, walked out of Stanislaus County Women's Facility on Oakdale Road on June 3, 1986, after serving a two-week sentence for a drug violation. She called her family on June 6th to let them know she would be home later in the day and that she would catch a ride to her Modesto home with her new boyfriend, whom no one in her family knew. She was last seen getting into a green or blue truck.

Some sources list May 29th or June 6th as her date of disappearance.
