Ricardo Medina Jr. now faces up to six years in a federal prison.
Medina released a statement upon his initial release from prison stating: "I want to say I am very, very, very sorry for what occurred", Medina told the media after his release. Sutter was taken to the hospital where he was pronounced dead. Medina claims he stabbed his roommate with his sword as an act of self defense.
Medina had initially entered a no contest plea on his manslaughter charge before amending it to guilty, the DA's office said.
He was then re-arrested in January 2016 and later charged with murder - but pleaded not guilty.
Josh's father Donald Sutter, however, denied the possibility that his late son may have been the aggressor in his fatal argument with Medina, according to a report from the Chicago Tribune. "Josh don't have that in his heart to attack anybody", he said.
Medina appeared in 40 episodes of "Power Rangers Wild Force" as Cole Evans in 2002, and returned to the franchise in 2011, appearing in 24 episodes of "Power Rangers Samurai". He also played the villainous character "Deker" in "Power Rangers Samurai" in 2011 and 2012, according to his IMDb profile.
As well as his roles in "Power Rangers", Medina had small parts on "ER" and "CSI: Miami".
