From what I can find out, the principal proposed expulsion- this was reported in the Alexandria, LA newspaper. A school district committee changed this to suspension for three days.

Mychal Bell's previous battery convictions would have been sufficient to net him serious felony charges anywhere on the December incident. His football ability was all that kept him in school; he no longer was on the team (eligibility expired, academic or other reason?).
The other defendants posted bail, but the judge, citing Bell's criminal record, kept the amount for him at $90,000, which the parents refused to post. The District Attorney reduced charges to second-degree battery, and offered a plea agreement including a suspended sentence, but Bell's family refused and went to the media.

A judge threw out the conspiracy charges and referred the case to juvenile court, but let stand a conviction for aggravated second degree battery.

The State's Third Circuit Appeals Court threw out the conviction on Sept. 14 because he should not have been tried as an adult.

The case will be tried in juvenile court unless the district attorney is successful in an appeal.

The noose incident, etc., happened a year ago, and the beating took place in December.

In the meantime, the arson that destroyed the school's main academic building, seemingly related to the situation, is still under investigation.

Looks to me like justice was proceeding slowly, but that often is the case in American courts.

If charges result from the arson investigation, look for the whole thing to be blogged to death and tried by outsiders again.
