Jacksonville Beach police have confirmed that they believe a “takeover” event at the beaches that ended in gun violence on Saturday has connections to the organizers of a similar event that also ended in gunfire at the Avenues Mall a week earlier.

A teen takeover is a large, loosely organized gathering of juveniles that’s typically promoted on social media and can quickly overwhelm the area where it happens — a mall parking lot, a popular park, or a busy shopping corridor.
