In this episode of Hunting 4 Answers: In March 2007, 20-year-old nursing student Kelly L. Allen disappeared without a trace after wrapping a successful job interview. The interview went so well that Kelly was actually scheduled for a follow-up interview later that day. However, she never showed. She left behind all of her belongings—and a $2,000 check. Years later, her cousin spots a woman who looks just like her on a train. Is it Kelly… or just a cruel coincidence? Anyone with information about Kelly's whereabouts should contact the Saint Louis Metropolitan Police Department at 314-444-5338. Her agency case number is 07-018933.
