New York (CNN) -- Federal investigators have joined local and state law enforcement in an effort to track down and prosecute Ann Pettway, who is suspected in the 1987 abduction of Carlina Renae White, according to a law enforcement source. A warrant was issued Friday in North Carolina for the arrest of Pettway, for violating her two-year probation sentence on attempted embezzlement charges, according to North Carolina Department of Corrections spokeswoman Pamela Walker. "As part of her probation she must seek permission to leave the state of North Carolina," Walker said. "At this time no such request has been made."
