18-year-old in critical condition after being hit by vehicle in Greenbelt

WASHINGTON- Chanos Monroe, also known as Chanos Gillis, 41, of District Heights, Maryland, pleaded guilty today to charges of voluntary manslaughter and unlawful possession of a firearm in connection with the 2022 murder of Keith Sistare, 52, at a BP gas station in the northeast. Washington, the US Attorney’s Office announced.

Monroe’s guilty plea is part of an agreement that calls for a sentence of 14 years in prison, followed by five years of supervised release. The plea, subject to court approval, comes after Monroe has been in custody since his June 25, 2024, arrest.

According to court documents, the incident occurred on September 11, 2022, when Monroe and an unidentified man chased Sistare after he attempted to get into Monroe’s idling vehicle, which was parked outside the station- BP service on Benning Road. Monroe’s fiancée was sitting in the front seat at the time of the attempted robbery.

Surveillance footage showed Monroe repeatedly stomping on Sistare’s head as he lay on the ground. After the attack, Monroe retrieved a handgun from his vehicle but was convinced by his fiancée to return to the car without using the weapon. Sistare later died from his injuries.

Monroe faces sentencing pending court approval of the plea deal.
