Aaron Hernandez just can't seem to stay out of trouble. The former rising NFL star, currently awaiting trial for murder, has reportedly gotten into a fight in a Massachusetts prison.  

USA Today is reporting that the fight happened at the Bristol County House of Corrections yesterday, and was separated by Bristol County Sheriff Thomas Hodgson. Neither man was seriously injured in the fight, but Hernandez and the other man are both undergoing an "internal investigation" at the prison to determine what started the fight, and who ultimately is to blame. 

In addition, according to ESPN, surveillance videos are being reviewed, and other prisoners are being interviewed, to ultimately determine what criminal charges -- if any -- Hernandez should face as a result of the fight. "An altercation took place between two inmates, and one of them was Aaron Hernandez,'' Hodgson said in a statement. "We will be studying video and proceeding with interviews to determine why and how the incident took place to determine whether internal discipline or criminal charges are warranted." 

Prior to the incident, Hernandez was being held in a segregated unit. Both he and the other prisoner have been moved to different units, pending the outcome of the investigation. 

On June 18, 2013, Hernandez's house in North Attleboro was searched by police for several hours in connection with an investigation into the shooting death of a friend, Odin Lloyd. Lloyd's body was found in an industrial park about a mile away from Hernandez's house with multiple gunshot wounds to the back and chest. Two days later, the Boston Herald reported that Hernandez had been "barred" from Gillette Stadium by the Patriots. On June 26, 2013, Hernandez was taken from his home in handcuffs and into police custody. The Patriots released Hernandez about 90 minutes later, before officially knowing the charges against him. Later that day, Hernandez was charged with first-degree murder, in addition to five gun-related charges; if convicted of first-degree murder, Hernandez faces life in prison without the possibility of parole.
