An actor who portrayed one of the “Power Rangers” in the children’s television show was charged with murder Thursday in the fatal stabbing of his roommate, prosecutors said.

Ricardo Medina, 36, will appear in court next week to answer charges that he killed his roommate, Josh Sutter, with a sword last year after they argued at the Green Valley, Calif., home they shared, according to a news release issued by the Los Angeles County district attorney’s office. Sutter was stabbed multiple times, the release said.

If convicted, Medina could face life in prison.

Medina was arrested on suspicion of murder on Jan. 31, 2015, shortly after the attack, police have said.

Medina entered his bedroom with his girlfriend after a confrontation with Sutter, who followed them into the room and forced the door open. Medina grabbed a sword that he kept near the door and stabbed Sutter multiple times in the abdomen, investigators said at the time. Prosecutors said the argument was “over Medina’s girlfriend,” but did not elaborate.

Medina called 911 and remained at the scene. He was arrested soon after, but the district attorney’s office did not file charges at the time.

The agency asked the Los Angeles County Sheriff’s Department to continue investigating the killing, according to Jane Robison, a spokeswoman for the district attorney’s office. Medina was arrested early Thursday morning, she said.

Aside from one-off appearances on “CSI: Miami” and “ER,” Medina was mostly known for portraying the Red Lion Wild Force Ranger in “Power Rangers Wild Force” from 2002 to 2003. He also played the villainous character “Deker” in “Power Rangers Samurai” in 2011 and 2012.

Gar Lester, Medina’s longtime agent, described him as a “trusted friend” who had never exhibited a violent streak. Lester did not think Medina had a criminal history prior to the arrest, though he hasn’t spoken to his client since the incident last year.

“I’ve known Rick for years. He really is one of the most peaceful guys. He was thrilled and loved being a Power Ranger. He rescued and trained a wonderful German shepherd, and he was a client and friend,” said Lester, who did not know the victim or Medina’s girlfriend. “It’s still very difficult for me to believe this was anything but self-defense.”
