Hundreds of angry activists converged on Tallahasee Tuesday, demanding justice for a teenager who died after being beaten by guards at a Florida "boot camp" prison, MyFoxTampa reported Tuesday.

Fifty-five busloads of protesters from throughout the state marched to the steps of the federal courthouse for the Justice for Martin Lee Anderson March and Rally, organized by the Florida NAACP. The protesters are asking the Justice Department to investigate whether Anderson's civil rights were violated when prison guards beat the 14-year-old after he collpased during a run.

Anderson died following the beating, which was caught on video tape. The seven prison guards who were shown on the tape beating Anderson, were acquitted of all charges, including manslaughter, in Anderson's death.

A nurse charged in the case was also acquitted.

Protesters also wasnt the investigation to include Florida Department of Law Enforcement Commissioner Guy Tunnell, who was accused of trying to keep the tape of the beating from being made public.

The verdict of the all-white jury in Panama City, Fla., in the death of the African American teen also sparked allegations of racism.

"We are putting word out that we are together in wanting something to be done, and we are asking that higher powers come in and look at this case," Pat Spencer of the NAACP told MyFoxTampa.

The Florida state Legislature agreed to pay Anderson's family $5 million earlier this year to settle civil claims in the case. The case resulted in boot-camp style juvenile facilities being shut down throughout Florida.
