A Bucks County mother who admitted making up a phony story about being kidnapped has also admitted stealing more than $700,000. 40-year-old Bonnie Sweeten of Feasterville pleaded guilty to wire fraud and aggravated identity theft Tuesday in federal court in Philadelphia.  About a year ago she told a judge she had no explanation for why she fled to Disney World with her nine-year-old daughter in May of 2009 after concocting a story about two black men carjacking them and shoving them into the trunk of a Cadillac on Street Road in Southampton.  In the latest case she admitted stealing from her employer and her ex-husband’s ailing grandfather, and stealing civil settlements awarded to a number of clients at the Feasterville law firm where she worked as a paralegal.
