Troubled actress Mabel Pantaleo has been found alive at New York's John F. Kennedy airport, said her mother, who reported her missing this week. Pantaleon, 31, who suffers from manic-depressive disorder, was last seen at her Manhattan apartment Sunday morning. Her mother Sylvia officially reported her missing Monday, but she wasn't found until Thursday night, said ABC News. Sgt. John Buthorn of the New York Police Department said New York Port Authority police picked Mabel up after her name registered in a police database while she was trying to buy a plane ticket. "She was in [Port Authority's] custody on Thursday evening. She was in good condition, and there was nothing suspicious," Buthorn told ABC News. Pantaleon was then taken to the psychiatric emergency room at Jamaica Hospital in Queens. Sylvia said she suspected her daughter had stopped taking her medication because her behavior was erratic the last time she saw her. "Everything is over, thank God. She's OK, and she is in the hospital," Mabel's mother told ABC News Friday. "Thank God for everything .. that this is over now." Mabel appeared on TV's "Dexter," "Mystery ER" and "Untold Stories of the ER," as well as the films "Choose Connor," "Double Down" and "The Gleam."
