SAN JOSE — A San Jose police officer accused of raping a woman was handcuffed Wednesday and taken to jail in tears by four court bailiffs after the District Attorney’s Office moved to charge him with new crimes that could put him in prison for life.

Officer Geoffrey Graves, 39, sobbed and said, “I love you” to his tearful father as he put his arms behind his back to be handcuffed and was taken into custody on the third day of his preliminary hearing.

Graves had been free on $100,000 bail since his arrest last March and still remains on paid administrative leave while Superior Court Judge JoAnne McCracken decides whether to hold him over for trial. He is currently facing 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 Santa Clara County prosecutor Carlos Vega sought Wednesday to file an amended complaint with 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.

The judge, who ordered that the officer be jailed, is set to decide Monday whether prosecutors can file the stiffer charges based on prosecutors’ argument that new information emerged during the preliminary hearing through witness testimony. She also will hear the defense’s argument for bail.

Earlier this week, at the beginning of his preliminary hearing, 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, Darlene Bagley 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. On Wednesday, Comstedt said Graves would plead to the original charges. But Vega argued that Graves forfeited his chance by forcing the witnesses to testify.

Comstedt then asked the judge for more time to prepare a legal brief to block prosecutors from increasing the charges. The judge allowed it, but she indicated she agreed with the District Attorney’s Office that new information emerged during the preliminary hearing that justified new charges.

Tuesday, Comstedt peppered the alleged rape victim with questions in an effort to undermine her credibility. The woman, who answered through a Spanish interpreter, faltered only somewhat over relatively small details like how long the alleged assault took and where she was standing in the hotel room when the officer allegedly barged in.

The rape charge against the officer stems from a Sept. 22 family disturbance call. According to court documents, the sexual encounter between her and Graves came after police responded to a call about the argument she and her husband were having. No arrests were made during that call. She chose to stay at the Marriott hotel on Saratoga Avenue in San Jose that night where she had worked as a maid and was escorted by two officers, including Graves. After waiting a short time, police said, Graves returned to the woman’s room.
