CHICAGO, IL (CNN) -- A 13-year-old boy in Chicago was shot and killed during a dispute, allegedly over a Facebook post.
Police say Anthony Diaz was shot in the chest as he was walking with a group. Diaz's sister says the teen wanted to back her up in a fight with some other girls over a Facebook post.
"We came, we fought. They just got out of hand. They jumped all of us and they ended up shooting my brother," said Jennifer Sosa, the victim's sister.
Police say the victim recorded the altercation on a cell phone, but it's not clear what the recording shows.
No arrests have been made.
