Nursing student Brittany Diggs explains how she managed to escape from the trunk of her car after being kidnapped. "I remember seeing a video on Facebook" about how to find a trunk's release latch, she told the Today show. "So I got the bright idea to use my insulin pump light." The Alabama woman said she was taken at gunpoint last week as she walked to her apartment. A man approached and demanded money, she said. "He was like, 'give me your pin number or I'm going to kill you,''' she recounted.
