I believe this is the same case where they tried to say the boy died because he had the sickle cell trait that led to his internal bleeding.  I think the coroner reversed that ruling and changed this to murder or intentional death.
The shame is that even with a videotape and the reversal from the coroner....no arrests have been made.  The parents and attorney were on the Today show several weeks ago when the coroner reversed its ruling.
Its seems that the fact that he was a "bad kid" somehow justifies beating him death.  The force was excessive.  The video shows about 6-7 grown men and a female nurse surrounding this kid who couldn't have been more than 150 pounds soaking wet.
