DC Superior Court Judge Maribeth Raffinan ruled that the prosecution failed to establish a formal identification of two codefendants who were charged with a jail stabbing. The finding came during a hearing on Oct. 29.

Koran Gregory, 20, and Byron Matthews, 19, were charged with assault with intent to kill while armed for their alleged involvement in stabbing an inmate at the DC Jail on the 1900 block of D Street, SE, on Sept. 12.

Gregory and Matthews have additional charges against them in other cases.

Gregory is currently facing charges for his alleged involvement in a fatal drive-by shooting that killed 10-year-old Arianna Davis on May 14, 2023 on the 3700 block of Hayes Street, NE.

Matthews is facing charges for his involvement in a mass shooting that occurred on April, 21, 2023 on the 500 block of LeBaum Street, SE and the 2900 block of 2nd Street, SE. Eight individuals sustained injuries.

Matthews took a plea deal for his involvement in the mass shooting in August which dropped counts against him from fifty down to three. Sentencing is pending for the case.

According to court documents, the jail stabbing victim had been transferred to the defendants’ residential unit. In just 15 minutes after arrival,, he was attacked by “three to four” individuals whom he could not identify. The victim was taken to the hospital to treat several injuries.

Ruling for probable cause was delayed to review all of the evidence that the prosecution provided — testimony from the lead detective from the Metropolitan Police Department (MPD) and surveillance footage from the day of the incident was provided on Oct. 29.

Before ruling, Judge Raffinan mentioned that the prosecution did provide sufficient evidence to prove that an incident occurred at the DC Jail on Sept. 12.

However, she added the prosecution failed to provide sufficient evidence proving Gregory and Matthews were the perpetrators. No formal identification process was conducted among witnesses or the victim.

Judge Raffinan found no probable cause for the charge of assault with the intent to kill while armed, dismissing the case. However, she informed the defendants the prosecution can pursue a grand jury indictment.

Defendants are not released due charges in other cases. No further dates were set.
