A pair of public works employees for Dauphin Island were jailed Tuesday on drug trafficking and other charges after authorities said they planned to sell one of the bricks of cocaine found on a city beach and split the proceeds.

Robert Manuel Butler and Dean Lewis Hazard were both charged with trafficking cocaine and second-degree tampering with physical evidence, according to Mobile County jail records.

Hazard and Butler work for the Dauphin Island Department of Public Works, the Mobile County Sheriff’s Office told Fox 10.

One of the city employees allegedly buried half the cocaine brick in his yard while the other stored the other in the freezer.

The sheriff’s office could not be reached to confirm the report.

People walking on West End Beach on Dauphin Island spotted the bundle of cocaine on Saturday, the Mobile County Sheriff’s Office said, according to WKRG.

Dauphin Island police used an ATV to recover the packages from the beach before turning the bundle over to the sheriff’s office.

It was unclear how long the suspected cocaine was on the beach, but the sheriff’s office said it appeared the packages were there “for some time.”

Drug traffickers sometimes use boats and airplanes to cross the Gulf of Mexico, and a Gulf Shores police spokesman earlier told AL.com that officials usually get calls about once a year about smaller amounts of drugs being found on beaches. With few clues to go on, police rarely determine the origin of the drugs.

Cocaine swept in from the Gulf last turned up on Dauphin Island in 2009, when two bricks were found by beachgoers.
