Disappeared (2010)

Season 4: Episode 5

Colleen Orsborn goes missing after skipping school for a day at the beach. Although the spontaneous, outspoken teen has been known to get into tussles with her mother, she usually leaves a note indicating where she will be, and she always returns home. Family and friends worry that something very sinister has happened, preventing Colleen from returning home. Then, when news breaks that a notorious serial killer named Christopher Wilder can be placed in Daytona Beach the day the teenager went missing, their fears could become warranted. The disappearance of Colleen is a baffling mystery that haunts Central Florida for decades, until one woman uncovers a clue that has been right under their noses for nearly thirty years.
