FULLERTON, Calif. -- Police say a Southern California officer charged with murder in the death of a mentally ill homeless man is no longer working for the department.

Acting Fullerton police Chief Dan Hughes said in a statement Tuesday that Manuel Ramos left the department July 3.

Hughes withheld further details, citing city personnel rules, but the Orange County Register reported in May that Ramos and the other officer charged in the case, Cpl. Jay Cicinelli, received letters from Hughes saying he intended to fire them.

Hughes said Cicinelli remains on unpaid leave.

The officers have been ordered to stand trial in the death of Kelly Thomas, who suffered from schizophrenia and died five days after a July 5, 2011, confrontation with six officers who suspected him of breaking into cars.
