SEATTLE - King County prosecutors say the three teenaged suspects in the slaying of the man Seattle sports fans knew as " Tuba Man" have pleaded guilty to the crime.
Edward McMichael, 53, was robbed and beaten to death near a bus stop on Mercer Street last November.
King County Prosecutor Dan Satterberg announced late Friday afternoon that one 15-year-old and two 16-year-olds pleaded guilty to first-degree manslaughter as juveniles.
Because the teens were 15 at the time of the crime with no prior criminal history, they could not be charged as adults.
Two of them also pleaded guilty to an additional charge for a robbery that happened just prior to the assault on McMichael.
The prosecutor says because no witnesses came forward, they could not move forward with a case without these guilty pleas.
Two could serve up to 72 weeks in juvenile detention, the third faces up to 36 weeks. They will get credit for time served.
McMichael was a fixture at sporting events, whether it was before a Seahawks game, a Sonics game or a Mariner's game - even outside McCaw Hall on opera nights. He would play his tuba and wear amusing hats.
