FULLERTON (CBS) — The Fullerton Police Department has decided to fire some of the officers involved in the fatal beating of a homeless man.

Police have confirmed that Officers Manuel Anthony Ramos and Joe Wolfe have received letters of intent to terminate. Sources tell CBS2 that Cpl. Jay Cicinelli also received the same letter.

Both Cicinelli and Ramos have been on unpaid leave for months. Wolfe is still being paid, pending his administrative hearing.

All three officers were involved in the beating that eventually killed Kelly Thomas, a homeless man who suffered from schizophrenia, last summer. Thomas died five days later.

Ramos and Cicinelli are facing serious charges — second-degree murder and involuntary manslaughter, respectively — and are headed to trial. Wolfe has not been charged.

“Ramos, he set the whole thing up. He is charged with second degree. Not only should he be terminated from the department but he needs to stand trial for the murder of Kelly and setting it all up. I want Wolfe not only terminated from the department, on the administrative side, but I want Wolfe charged with Kelly’s murder. He’s the one who hit him initially with the baton. He’s also the one dropping the two huge elbows, just breaking Kelly’s face apart,” Kelly’s father, Ron Thomas, said outside the courtroom Tuesday.

The officers have 10 days to respond to the letters of intent to terminate or they’ll be fired. The attorneys for Ramos and Wolfe said they haven’t decided yet how they’ll proceed.
