(CNN) Apple thieves snuck onto a Michigan family farm and stole more than 3 tons of fruit right off of the trees.

The heist was discovered October 10, when workers from Spicer Orchards came to pick the fruit, Shannon Rowe told CNN on Thursday. Her parents own the orchard and she's a partner in the business.

"We are just shocked and stunned," Rowe said. "We just can't believe it happened. It was last week during the night. It wiped out most the apple crop."

Spicer Orchards is a popular fall destination near Flint, where families come to pick their own apples and enjoy cider, donuts and other treats.

Rowe said the theft happened at a secondary orchard, where they grow apples for cider and to sell in their market. She said they'd checked the apples a few days earlier to see if they were ready to pick.
