A former D.C. corrections officer has been charged with a federal civil rights violation for assaulting a handcuffed and detained individual, U.S. attorney for D.C. Matthew Graves announced Wednesday.

A grand jury indicted the officer, Marcus Bias, for using unreasonable force. (An indictment is not a statement of guilt, but rather an allegation.) Bias pushed the head of a person being held pre-trial into a metal doorframe while escorting him within the Department of Corrections in 2019, resulting in an injury, according to Graves’ office.

He faces a maximum statutory penalty of 10 years in prison, a term of supervised released, and fines. The FBI’s Washington field office investigated the case, and it is being prosecuted by the Civil Rights Division’s criminal section and Assistant U.S. Attorney Michael Truscott.

It’s the U.S. Attorney for D.C.’s second case against a D.C. corrections officer in recent months. In late September, officer Beverly Williams was arrested and charged with conspiracy, bribery, and smuggling in connection to an alleged scheme to bring prohibited drugs into the D.C. Jail. Months earlier, in February 2022, another officer was arrested for allegedly bringing drugs, knives, and cellphones into the jail in exchange for money.

Meanwhile, eight people have died in DOC custody in 2022. Most recently, 63-year-old Giles Warrick, referred to as the alleged “Potomac River Rapist” was found unresponsive in his cell on Nov. 19. His trial for a series of violent crimes in the 1990s was set to begin on Nov. 30. Others who have died in DOC custody include Giovanni Love and Treyvon Littles, two men whose families are still searching for answers about their deaths. Love’s death was ruled a suicide, and the medical examiner’s office recently determined that Littles died of an accidental overdose. Half of the deaths in DOC custody this year have been due to an overdose.

In a statement to DCist/WAMU on Wednesday, a spokesperson for the DOC said the department was aware of the conviction.

“As an agency we have a responsibility to protect the health and wellbeing of the men and women in our care,” the spokesperson wrote over email. “We have zero tolerance for physical abuse or any unnecessary/excessive use of force.”
