Store manager Zane Kishbach said a customer alerted him to the woman.

"Another customer came to me in aisle 5 and said, 'I'm not sure what I'm seeing, but I think a woman is stealing,' and she had already left the store by that time, and I went out to pursue her," Kishbach said.

WNEP reported that workers were able to get the woman's license plate from the car.

When police tracked it down, they found that the car Pennino was driving in was owned by Saints Cyril and Methodius Convent.

They discovered that the thief is a nun who lives at the convent.

"I was shocked," Kishback said. "I couldn't believe it that a nun would do that."

"Humanity's gone to hell, to put it bluntly," shopper Wendy Everett said. "It's not good anymore."

Officials think she planned the shoplifting and came in with the store's red grocery bags so she could put the shoplifted items in them.

When another customer triggered the store's automatic doors and entered the store, Pennino ran out.

Inside Edition reported that Pennino stole $23 worth of snacks, shampoo, coffee and soap, according to Pennsylvania State Police in Columbia County.

Police spoke with the sister and determined that she was of sound mind.

She is charged with a summary offense, which police said means she would pay a fine in exchange for a guilty plea.
