WAUKESHA, Wisconsin (AP) — A girl stabbed 19 times, allegedly by classmates trying to please a fictional online character, has received a military award from an anonymous donor.

The girl's family had asked that well-wishers send her purple hearts, reflecting her favorite color and shape, and the 12-year-old was inundated with paper hearts from across the country. Then one person sent her the real thing.

The girl's family said Tuesday that the medal came with a card that read: "The only heart I could find! Be strong!"

The military awards the Purple Heart to veterans wounded or killed in action.

Investigators say the girl nearly died in May after being lured to a park and attacked by two 12-year-old girls after a sleepover outside Milwaukee. She's now recovering at home.
