SIERRA VISTA, AZ - The FBI says a former Cochise County detention officer is in custody in connection with a drug case.
Federal authorities say 31-year-old Mark Melgoza is accused of possession with intention to distribute controlled substances.
The county Sheriff's Department says it received a tip that Melgoza allegedly was involved with illegal drugs.
The department asked the FBI to launch an investigation and about 300 pounds of marijuana and a small amount of cocaine allegedly was found in Melgoza's home.
They say Melgoza was arrested Thursday and resigned from the sheriff's department on Friday.
FBI Special Agent Manuel Johnson says the agency's investigation is ongoing.
Authorities didn't immediately know Friday if Melgoza has an attorney yet.
