WEST PALM BEACH, Fla. (AP) - A 24-year-old man serving time for the fatal shooting of his middle school teacher says his civil rights have been violated.

 Beach Post reports the lawsuit, filed by Nathaniel Brazill in April, alleges prison officials transferred him twice and put him in solitary confinement in retaliation for filing a 2009 lawsuit against a warden.

Brazill, who represents himself, was 13 when he shot Barry Grunow on the last day of school in Palm Beach County in 2000.

The lawsuit is assigned to a federal judge in Fort Myers. Brazil claims the transfers were unconstitutional and seeks monetary damages against prison officials. The docket indicates lawyers for prison officials have not yet responded.

Brazill is currently serving his 28-year sentence at Hardee Correctional Institution in southwest Florida.
