LEE’S SUMMIT, Mo. -- (WDAF) -- Police are looking for two women they say tried to steal a senior citizen's purse outside Wal-Mart near Highway 291 and NE Tudor Road Tuesday around noon. Good Samaritans stepped in and stopped the two women from getting away in a vehicle, forcing them to stop driving and hand the purse back to the victim.

"They are going to get caught, and I am going to make sure I go to court and testify," said Jim Wilkins, who witnessed the entire thing. "I'm going to see to it that they get as much time as the law will allow."
