Details of Disappearance
Alfonso was dropped off at the Marathon Movie Theater in Marathon, Florida on August 20, 1974 with her friend Cynthia Gooding. They planned to hitchhike to a party that day. Neither of the girls has been seen again.Investigators initially believed Gooding and Alfonso had run away from home, as one of them had a history of such behavior. They are no longer thought to have left of their own volition, however. The police file for the girls was destroyed in a fire sometime after they vanished. Both cases remain unsolved.
