The Montgomery police officer arrested on drug charges on Tuesday was found in possession of cash used in an undercover drug buy that took place at her residence, court documents claim.

Amanda Millwood, 38, who has served as a Montgomery police officer for nine years, is charged with two counts of unlawful distribution of a controlled substance, records show.

Montgomery police claim Millwood was involved in the sale of heroin to a confidential source with the Montgomery Police Department at her residence on Eton Road on May 9. Millwood was later found to be in possession of the cash used in the drug buy, her arrest warrant states.

Millwood's co-defendant, Constance Millwood, 34, who also lives at the residence on Eton Road, was also implicated in the drug deal. She was found in possession of cash used in the buy, court records show.

Beverlee Gardner, 36, was charged with unlawful possession of a controlled substance in connection to the same drug transaction. Her arrest warrant wasn't immediately available.

Capt. Regina Duckett said Millwood was placed on mandatory leave following her arrest. Disciplinary action against the officer was initiated, she said.

Duckett said no update on Millwood's employment with the police department was available on Thursday morning.

Amanda and Constance Millwood were released from the Montgomery County Detention Facility after posting $10,000 bond each. They are set to make their first court appearance on Thursday afternoon.

Gardner remains in jail on a $1,500 bond and probation violation.
