Two college students have returned a purse -- and a life's savings -- to an Arizona woman. On Monday, the students spotted the purse in a gutter in Casper, Wyoming. They picked it up and gave it to police after discovering an Arizona driver's license in a wallet inside. Police say the students didn't see an envelope packed with 43-thousand dollars in cash. Police say the owner had been traveling through the town and misplaced the purse during a stop. She phoned one of the students to promise a 200-dollar reward. The student says he can't believe they had that much money in their hands "and didn't even know it."
