The fifth Maryland teenager charged as an adult in the armed robbery and subsequent fatal stabbing of an Olney man for his designer jacket was ordered on Monday to remain in D.C. jail until trial.

D.C. Superior Court Magistrate Judge Frederick J. Sullivan ordered Tyvell Smith, 17, to remain in jail on charges of armed robbery of one of Olijawon Griffin’s friends as they were waiting for their train at the Woodley Park Metro station Nov. 17. Minutes before the attack, Griffin, 18, was robbed of his designer $400 Helly Hansen jacket blocks away near a gas station by Smith’s friends, prosecutors say.

Prosecutors say Smith was one of a group of about 12 teenagers who attacked Griffin and the unidentified victim in the Metro station. During the attack, which was caught on Metro security video, Griffin was fatally stabbed by one of Smith’s friends, Chavez T. Myers, also 17. Myers is charged with second-degree murder in Griffin’s death.

Nine teenagers, including Smith, have been charged in the robbery and attack on Griffin and the robbing of his friend. Smith’s next hearing is set for Jan. 7.
