New details on that deadly incident in the sand on a beach in Florida. Sheriff's deputies have now identified the 7-year-old girl who died after a sand hole she was digging with her brother collapsed and caved in on them. Sloan Mattingly was vacationing in Lauderdale-by-the-Sea, with her family earlier this week from Indiana. While the incident was tragic, lifeguards say it is not uncommon. Witnesses say it took about 15 minutes to reach Sloan after they got her brother out. MORE: https://abc7.com/child-dies-in-sand-hole-collapse-fort-lauderdale-florida-killed/14452441/
