Three helicopters around Ft. Lauderdale beach

Watching two helicopters hover and a coast guard helicopter come in low from the north along the coast. Looks like they’re out by Fort Lauderdale beach. Anybody know what’s going on?

Edit: Broward county sheriff helicopter not coast guard. Two news helicopters are the ones above. Missing swimmer: https://wsvn.com/news/local/broward/crews-searching-for-missing-swimmer-off-fort-lauderdale/
