A judge increased bail from $350,000 to $1 million on Nov. 10 for each of four men suspected in the Nov. 5 home-invasion robbery of La Jolla cookbook author and philanthropist Jeanne Jones. Deputy District Attorney C.J. Mody told San Diego Superior Court Judge Richard Whitney all four men are residents of San Bernardino County and they committed “a very sophisticated crime.” He said the men had no ties to San Diego, making them a flight risk. Mody said a caretaker, Dorta Jochum, heard a knock at the door around 6:30 p.m. on Nov. 5 and saw a man outside holding a single rose. The man said, “I have a flower for Jeanne Jones” and Jochum opened the door. Mody said the men then punched and hit Jochum in the face and she was violently knocked to the floor. At least two other masked men then burst inside and, at gunpoint, ordered Jones to open a safe containing jewelry in an upstairs bedroom. At gunpoint, Jones gave the men gold, jewelry, rings and watches, which were valued at $30,000, according to the prosecutor. Police later recovered the jewelry. All four men are charged with robbery, residential burglary, felony assault, elder abuse and receiving stolen property. They all pleaded not guilty. Mody said they face 20 years in prison if they are convicted of all charges. Thomas Walter Clark, 41, Hector Guerra, 30, Aaron Jacob Espinoza, 23, and Miguel Ocegueda, 23, all waived having their high bail reviewed after talking to their lawyers. When the attorneys get more information about their clients, they could return to court to seek a bail reduction. The men will attend a status conference in court on Nov. 24, and a preliminary hearing has been scheduled for Dec. 20. Jochum, who is in her 50s, developed “a very severe black eye” and suffered lacerations, Mody said. An icepack was placed on her face and she was taken to the hospital. A United Parcel Service driver had a package to deliver to Jones just minutes after the men burst inside. He saw three men wearing ski masks, so he ran back to his truck to call 9-1-1. The men left and he began following them while on a cell phone with police, Mody said. As the men were driving off, the ski masks, gloves and possibly one or two guns were dropped from their SUV as they sped off. Due to the tip by the UPS driver, police pulled over the SUV on State Route 52 just west of Regents Road. Mody said the investigation is ongoing and the men may face more charges. Jones did not attend the Nov. 10 arraignment because she was in the hospital for an unrelated knee surgery. She writes a nationally syndicated food column called “Cook it Light.”
