Former NFL star Aaron Hernandez, who is in jail awaiting trial for the first-degree murder of Odin Lloyd, was indicted Thursday for a July 2012 double murder. 

Hernandez, 24, who formerly played for the New England Patriots, has been charged with fatally shooting two men in a drive-by, according to CBS Sports. 

The weapon that was used in the shooting was recovered in August 2013. Two months later, a man who survived the drive-by identified Hernandez as the person who fired the weapon. 

Relatives of the two slain victims, Daniel Abreu and Safiro Furtado, said neither of the victims knew Hernandez. Both of the victims worked for a cleaning company, and neither one had a criminal record. 

The shooting took place at a red light after the men had left the Cure Lounge, a club in Boston's south end. 

"They just came up and started firing for no reason at all," the eyewitness told Fox 25 last year. "We never had any trouble. We were not those kind of people. We were just having fun ... Things happened so fast. I was trying to defend myself. They were shooting everywhere inside the car, front to back. They just came to kill. That's it."

The witness, who remains anonymous, said he recognized Hernandez's face when he was arrested last summer for Lloyd's murder. 

While the motive for the murders is unclear, if Hernandez is found guilty, it means that he played an entire season in the NFL after murdering two people. 

Hernandez was a fourth-round pick in the NFL 2010 draft by the Patriots, then the team signed Hernandez to a five-year extension in August 2012. 

Hernandez has pleaded not guilty to the first-degree Odin Lloyd murder charge. 

Hernandez allegedly picked up Lloyd from his apartment in Boston in a rental car shortly before Lloyd was found fatally shot on June 17. 

Lloyd was found dead in an industrial park near Hernandez's North Attleborough home. 

According to authorities, surveillance cameras show the rental car leaving the scene of the crime, and Hernandez carrying a gun when he returned to his home shortly after. 

He was also indicted a few weeks ago on charges related to a jailhouse fight, according to the district attorney's office in Massachusetts. 

A grand jury in Bristol County indicted Hernandez on charges of assault and battery stemming from the jailhouse altercation on Feb. 25, according to CNN. 

He was also indicted for threatening to do physical harm to someone who worked at the jail in November. 

The date for Hernandez's arraignment has not yet been set.
