On August 22nd, 19-year-old Aaron Arias and his 17-year-old friend Jamal Harris were sitting at a stoplight in Dallas, and they started checking out a woman who was sitting in the backseat of the car next to them. They noticed the driver looking back at them, and felt like something wasn't right. Then they saw the woman mouth the words "help me," so they followed the car. Aaron got on the phone to 911, and it turned out the 25-year-old woman had just been KIDNAPPED an hour earlier. Police showed up immediately, pulled the car over, and arrested the driver . . . Charles Atkins Lewis Jr., who's charged with aggravated kidnapping. The woman says Aaron and Jamal saved her life, and she was able to thank them after it was all over. Here's Aaron in the 911 call, where midway through a police officer catches up to the kidnapper.
