Self-proclaimed White supremacist Calvin Lockner pleaded guilty on Sept. 22 in the brutal 2009 attack on a Black fisherman.

According to NBC Baltimore affiliate WBAL-TV, 76-year-old James Privott was attacked by three White men while attending a fishing trip with his wife at Fort Armistead Park near Baltimore in 2009.

Lockner, the alleged leader of the attack, pleaded guilty to first-degree assault, a hate crime charge and an attack on a corrections officer in May. He also faces time for carjacking Privottโ€™s truck before the attack. If convicted, his prison sentence could span more than three decades.

โ€œItโ€™s safe to say that this is a plea agreement that we feel really good about because weโ€™re going to get this person off the streets for 31 years,โ€ State Attorney Joe Sviatko told WBAL-TV.

Authorities said 28-year-old Lockner, along with teens Emanual Miller and Zachary Watson, continually beat Privott with a stick while he was fishing. Reports say that the n-word was spewed during the beating, which Lockner claimed wouldnโ€™t have happened if Privott โ€œhad been a White man.โ€ Following the incident, Privott had a broken eye socket along with many other injuries.

Miller was sentenced in juvenile court early this year, while Watsonโ€™s trial is scheduled for Sept. 27.

Lockner is a convicted sex offender who claims ties to two White supremacist groups, including the notorious prison gang the Aryan Brotherhood, according to the Associated Press.

Baltimore City is about two-thirds Black and police actively monitor the cityโ€™s White supremacists.

โ€œBaltimoreโ€™s a big city,โ€ Police Commissioner Frederick H. Bealefeld III told the AP during the time of the attack. โ€œJust as assuredly as we have Bloods and Crips, we have DMI and we have Aryan Nation and we have outlaw motorcycle gangs and we have MS-13.โ€
