SAN JOSE — His hands manacled to a chain around his waist Friday, the San Jose police officer accused of rape appeared in court clad in full jail garb for the first time since his arrest more than 11 months ago, including a yellow and red uniform marking him as a maximum-security inmate on suicide watch.

Officer Geoffrey Graves’ attire was a far cry from his appearance earlier this week when he came to court for his preliminary hearing in a white, cuff-linked shirt and black slacks. At the time, he faced three felony charges that could put him in prison for about 13 years: the alleged Sept. 22 rape of a woman he met on a disturbance call and two counts of domestic violence against an ex-girlfriend, who works for San Jose police as a dispatcher.

But after both witnesses testified, prosecutor Carlos Vega moved Wednesday to charge Graves with new no-bail crimes that could put him in prison for life, and he was taken into custody in tears. He remains on paid administrative leave.

Jail officials refused to comment Friday on whether they have Graves on a suicide watch. But under the jail’s classification system, inmates who need to be checked on regularly to make sure they don’t kill themselves are clad in yellow shirts, as Graves was wearing in court. The officer, however, appeared relaxed and even smiled a few times while conferring with his lawyer Darlene Bagley Comstedt.

Superior Court Judge JoAnne McCracken said she will decide next week whether to let Graves to plead no contest to the original charges, as his lawyer offered both on Wednesday and Friday, or to allow the prosecution file the stiffer new charges.

Vega is seeking five new allegations or enhancements that carry a possible sentence of 39 years to life in prison. The proposed new complaint includes multiple enhancements for “use” of a gun, being “armed” with a gun and unlawful entry with intent to commit rape. The judge will also hold a bail hearing next week.

But McCracken reiterated Friday that she agrees with the prosecution that the testimony of the alleged victims is evidence of a “sufficiently changed circumstance,” the legal standard necessary to warrant new charges and bar the plea.

“It’s a very different complexion now,” she said, referring to the case against Graves.

At the beginning of his preliminary hearing Monday, Graves rejected an offer by Vega to plead guilty to the original three charges, or face even more serious charges. An early admission would have spared the alleged rape victim and the ex-girlfriend from having to testify, said Vega, who was a police officer before becoming a lawyer.

Graves and his San Francisco attorney, Comstedt, declined the offer, gambling that the evidence would not be that strong, and that the offer would still be open at the end of the preliminary hearing, before the judge ruled on whether to hold him over for trial. Vega contends that Graves forfeited his chance to take advantage of the original offer by forcing the witnesses to testify.
