Carmen: SOMETIMES A STRANGER CAN APPEAR OUT OF NOWHERE AT JUST THE RIGHT TIME TO DO SOMETHING GOOD. THAT'S WHAT HAPPENED IN SOUTHFIELD AFTER A PURSE SNATCHER GOT WHAT HE WANTED FROM A LOCAL MOM LOADING GROCERIES INTO HER CAR. AS OUR LAUREN PODELL REPORTS, THAT WOMAN GOT SOME UNEXPECTED HELP FROM A GOOD SAMARITAN. Lauren: A LOCAL WOMAN WAS LEAVING THE MARKET HERE IN SOUTHFIELD. BEFORE SHE COULD UNLOAD HER DEGREES RIS, HER PURSE WAS SNATCHED OFF HER SHOULDER. ONE GOOD SAMARITAN SAID, NOT IN MY CITY! I SEE A GUY TAKE THE PURSE OFF A LADY'S SHOULDER AND HER SCREAMING, "HELP ME, HELP ME, SOMEBODY HELP ME!" Lauren: IT TOOK AN UNEXPECTED TURN WHEN A PURSE SNATCHER WAS NOT ONLY CAUGHT ON CAMERA BUT CAUGHT BY AARON TOBIN. I'M NOT SOMEONE WHO STANDS AND WATCH. LIFE IS A PARTICIPATION SPORT. Lauren: HE SCOPES OUT THE SHOPPERS AND HIS VICTIM IS THIS MOM WITH A FULL CART OF GROCERIES, TWO KIDS BY HER SIDE. THAT'S WHEN HE MADE HIS MOVE FOR HER PURSE. THE VICTIM STARTED SCREAMING FOR HELP, THAT'S WHEN AARON MADE HIS OWN MOVE. I TOLD HER TO CALL 911. SHE SAID, HE'S GOT MY PHONE, MY WALLET, EVERYTHING. SO I WAS INTENDING TO CHASE HIM ACROSS THE STREET. Lauren: THE SUSPECT WAS AT THE DUNKIN' DONUTS ACROSS GREENFIELD. HE FOLLOWED IN HIS TRUCK BUT EVENTUALLY GOT ON FOOT HIMSELF. I CHASED HIM AND I YELLED AT HIM AGAIN TO STOP IN THE PARKING LOT HERE AND HE TURNED AROUND AND THAT GAVE ME AN OPPORTUNITY TO JUMP ON HIM. Lauren: WITH HELP FROM ANOTHER SHOPPER, THIS PURSE SNATCHER DIDN'T HAVE A CHANCE. HE WAS FACEDOWN ON THE GROUND WITH BOTH ARMS BEHIND HIS BACK WITH TWO ADULT MALES SITTING ON HIM. HE RISKED HIS LIFE TO DO SOMETHING LIKE THAT. THIS GUY COULD HAVE PULLED A GUN OUT. Lauren: BUT HE DIDN'T, SO POLICE ARRIVED AND GOT THIS GUY OFF THE STREET. AND THIS SHOPPER IS GLAD PEOPLE LIKE AARON ARE OUT THERE. A LOT OF US ARE GUILTY OF LEAVING THE PURSE IN THE BASKET AND FORGETTING TO LOOK AT IT AND LEAVING IT WIDE OPEN BECAUSE YOU TRUST PEOPLE.
