The Nevada attorney general is charging a former prison guard trainee with manslaughter in the shooting death of a handcuffed inmate in a prison hallway two years ago.

A criminal complaint filed Monday accuses Raynaldo-John Ramos of firing the shotgun blasts that killed Carlos Perez Jr. while Perez and another inmate brawled at High Desert State Prison outside Las Vegas in November 2014.

Ramos also is charged with felony reckless disregard. A conviction on both charges could get Ramos up to nine years in prison.

Two other guards weren't charged. They resigned last May and were found to have made false statements and neglected their duty in the shooting.

They're named in a separate wrongful-death lawsuit.

The Nevada Department of Corrections dismissed Ramos in April 2015.
