Prosecutors alerted DC Superior Court Judge Michael Ryan they plan to retry a homicide defendant’s case following a mistrial, despite his co-defendant’s mental incompetence finding on June 2.
Robert Carpenter, 47, is charged with second-degree murder while armed, possession of a firearm during a crime of violence, and unlawful possession of a firearm with a prior conviction, for his alleged involvement in the fatal shooting of 42-year-old Tremaine Nicholson. The incident occurred on the 3400 block of 25th Street, SE, on May 7, 2024.
Aillayh Carter, 29, is charged with two counts of obstruction of justice for her alleged lying to the Metropolitan Police Department (MPD) about Carpenter’s involvement.
During the hearing, prosecutors alerted Judge Ryan they plan on retrying Carpenter following a mistrial on May 13 after the jury failed to reach a unanimous verdict on all the counts. Prosecutors further stated they plan to try Carter alongside Carpenter.
Question’s about Carter’s competency have complicated the case. A further evaluation was ordered by Judge Ryan. In order for a defendant to stand trial they must be able to understand the charges against them and participate in their own defense.
The trial is slated to commence on March 16, 2026.
Parties are slated to reconvene Oct. 31.
