'Serial stowaway' with history of sneaking on flights arrested at Chicago O'Hare

A woman with a history of being a "serial stowaway" and sneaking on flights was arrested at Chicago O'Hare International Airport after police were tipped off by her ankle bracelet, officials said Wednesday. Marilyn Hartman, 69, was already awaiting sentencing for trying to sneak on a commercial craft when her GPS ankle bracelet went off at about noon on Tuesday, according to a statement from the Cook County Sheriff's Office. The alarm indicated Hartman was outside "the residential facility where she" had been mandated to stay, the statement said. After Hartman didn't pick up her phone, authorities said they spotted the ankle bracelet headed toward O’Hare. She arrived at Terminal 1 at about 1:38 p.m. CT and an "alarm siren was activated on Hartman’s device" leading to her arrest by Chicago police before she could "enter any secure areas," the sheriff said.<br/>
