Four years before she became the innocent victim of what may have been a gang turf war, Hadiya Pendleton starred in an anti-gang public-service video.

She was a sixth grader at Carter G. Woodson Elementary School when she delivered a message against the kind of violence that led to her death in a Chicago park on Tuesday.

"Hi, my name is Hadiya... this commercial is informational for you and your future children," she says in the video, which was first reported by DNAinfo.com.

"So many children out there are in gangs, and it's your job to say no to gangs and yes to your future."
