The Coast Guard has suspended its search for three people aboard a Lancair single-engine plane that crashed Monday in the Mississippi Sound.

Gerald Miletello of West Monroe, Louisiana, along with Dexter Brewer of Saucier, Mississippi, and pilot Ron Gregory have been missing since their aircraft disappeared just minutes after taking off from the Million Air terminal at Gulfport-Biloxi International Airport.

Part of the tail was found on an Ocean Springs beach Tuesday, and officials had been searching nearby waters.

Capt. Brandon Lechthaler, deputy commander, Coast Guard Sector Mobile, said in news release that suspending a search is a difficult decision to make.

According to the news release, the Coast Guard and response crews covered more than 3,500 square miles in their search efforts.
