6-year-old Ilene was last seen outside her family's mobile home in Carson, California on December 20, 1980, a day after her 6th birthday. She was roller-skating outside her home and disappeared.
Her skates were found inside the front door of her family's house, but her shoes were missing.
Ilene's parents divorced after she disappeared and they believe she's deceased, but they continue to search for her.
Her nickname is "Becky" (after her middle name, Rebecca) and she has a brown-colored birthmark on her right hip. She was last seen wearing a pink or red blouse and long green pants.
