Rip currents kill 4 in 48 hours: Panama City Beach on pace to be deadliest in US

Deadly rip currents off Panama City, Florida, killed four people within 48 hours, a tragic toll setting the area on pace for another year as one of the country's deadliest beaches.

The bodies of three young men were found, one by one, Friday evening, authorities said. They had traveled to Panama City from Alabama just a few hours earlier.

On Thursday afternoon, rescue officials attempted in vain to save a 19-year-old swimmer behind Sharky's Beachfront Restaurant in Panama City Beach.
