The officers still have several chances to appeal.
A judge on Tuesday delayed their arraignment to give defense attorneys more time to work on a motion to dismiss the charges. The arraigned was delayed to June 26.
Thomas, a schizophrenic homeless man, died last July after a confrontation with police officers. He was allegedly trying to break into cars at the bus depot at the Fullerton Transportation Center.
Prosecutors allege Ramos punched Thomas in the ribs and tackled him to the ground, and minutes later Cicinelli Tasered him several times and struck him in the face eight times with the Taser.
Ramos is charged with second-degree murder and involuntary manslaughter in Thomas' death. Cicinelli faces charges of involuntary manslaughter and use of excessive force.
CORRECTION: It was previously reported that Manuel Ramos had been fired, but authorities clarified that Ramos has received a letter of intent to discipline/dismiss. This letter starts the process, but the officer has several chances to appeal.
