PASCAGOULA, Miss. – Two of the three men who were aboard a single-engine plane that went missing in the Mississippi Sound on Monday work regionally for a Cumming-based contracting company.

The plane went missing shortly after taking off from the Gulfport-Biloxi International Airport on Monday afternoon, according to the Associated Press, spurring a search-and-rescue mission by the Coast Guard.

Debris, including a piece with a part of the plane’s registration number, was found Tuesday.

Bob Roy, president of the contractor RMR Mechanical, told the Sun Herald that two of the three onboard were the company’s manager, Dexter Brewer, and vice president and co-owner Gerald Miletello.

Neither man works from the Cumming office, according to officials with the company.

RMR Mechanical, which provides contracting and mechanical services for clients throughout the Southeast, has a physical and mailing address in Cumming and a second location in West Monroe, La.

The third person was the pilot, according to the AP. Officials have not released names.

Roy said Brewer, who has worked with the company for about a decade, was headed to a customer meeting in South Carolina.

Brewer’s wife, Tina Cook, told the Herald she is hopeful her husband is alive. She said before he boarded, he told her they would probably fly along the coast to avoid rough weather.
