Sister Lynn Rettinger didn't even have to break out a ruler for man who reached into an open window and stole a wallet from a car on Tuesday. She just needed the voice honed by nearly 50 years in Catholic schools.
After a teacher saw the man swipe the wallet, the 5-foot-3 principal of Sacred Heart Elementary School in the Shadyside neighborhood went outside and firmly told the man, "you need to give me what you have."
The unknown thief turned over the wallet, apologized and walked away.
Rettinger says she merely said what she says to students when she knows they have something they shouldn't.
Police are still looking for the man.
