Florida ? Seven former guards at a juvenile boot camp were charged with aggravated manslaughter of a child Tuesday in the videotaped pummeling of a 14-year-old boy who later died – a case that led to the dismantling of Florida’s military-style detention system for young offenders.

Also charged was a nurse who can be seen on the tape watching as guards repeatedly kneed and hit Martin Lee Anderson during a 30-minute scuffle on Jan. 5. Guards said the boy was uncooperative and had refused to participate in exercises.

The teen collapsed in the exercise yard at the camp in Panama City and died at a hospital the next day.

The death sparked protests at the state Capitol and led to a shake-up in Florida’s criminal justice system and the resignation of Florida’s top law enforcement officer.
