Four bodies have been recovered in the Florida Everglades, days after two small planes collided in midair.

A spokeswoman for the Broward Sheriff's Office says the bodies of Bryan Sax of Aspen, Colo., and an unidentified person were brought in by airboat around 11 a.m. The bodies of Stuart Brown of Pembroke Pines and Edson Jefferson of Miramar were found a short time later.

The planes departed Saturday afternoon from Fort Lauderdale and Hollywood airports. The planes' wreckage was spotted the next morning about 25 miles west of Fort Lauderdale.

Investigators scoured the wreckage Monday. The swampy area is accessible only by airboat.

The cause of the crash is not yet known.
