Sandra Parks, 13, who wrote an award-winning essay about gun violence, was killed by a stray bullet on Monday as she watched television at her Milwaukee home.

“Little children are victims of senseless gun violence,” she wrote. “I sit back and I have to escape from what I see and hear every day. When I do; I come to the same conclusion … we are in a state of chaos,” CNN reports.

Last year, Parks told Wisconsin Public Radio that she chose to write the essay about gun violence because it was “all you hear about.”

Two men have been arrested and charged with Parks’ shooting death, though it is not clear why her home was targeted.

“All you hear about is somebody dying or somebody getting shot and people do not just think about whose father or son or granddaughter or grandson who it was that was just killed,” Sandra Parks told WPR.
