Prosecutors say Medina stabbed Joshua Sutter several times following an argument regarding his girlfriend inside their home in Green Valley, a town just outside Los Angeles.
The actor could face up to 26 years to life in prison if convicted. Medina has maintained that the attack was in self-defense.
Authorities had arrested Medina following the incident in January of 2015 but was released shortly afterwards.
"I want to say I am very, very, very sorry for what occurred. I'm very happy to be out of jail and my heart goes out to the Sutter family," he said following release.
Sutter's sister Rachel Kennedy spoke out against Medina's claims of self-defense previously stating, "I won't give up, and I won't let my little brother's voice ever be stopped. I will speak for him and fight for him forever."
