One of three teens convicted of killing Seattle's "Tuba Man" has will remain detained pending a trial related to a January robbery committed shortly after his release in the manslaughter case, a King County Juvenile Court judge ruled Monday.

The youth, 16, was part of a group of teens who attacked Edward McMichael – a well-known street musician who'd long been a fixture at Seattle sporting events – in October 2008. McMichael, 53, died after being released from the hospital from injuries sustained during the attack; three teens pleaded guilty to manslaughter charges in the attack.

Now, the teen is expected to go to trial in early August on robbery charges related to a Jan. 22 incident at a Central District youth center. The alleged robbery occurred shortly after the boy completed his sentence in McMichael's death.
