Los Gatos/Monte Sereno police have released a sketch of one of several assailants wanted in connection with the slaying of a former winery owner inside his mansion.

The man is believed to have been involved in the killing of Raveesh "Ravi" Kumra, 66, whose body was found early Friday by police after they were summoned by the victim's wife, Harinder Kumra, 63, to their ransacked, 7,000-square-foot home on Withey Road.

Police have declined to say how the former owner of Mountain Winery in Saratoga and cell phone entrepreneur was killed, saying they wanted to protect the integrity of the investigation. His wife was injured during what police said was a predawn home-invasion robbery. After the attackers fled, the woman called 911 about 1:40 a.m. Friday.

Police have not said whether the robbers took anything from the four-bedroom, seven-bath home that sits on 3 acres behind a brick wall, a mechanical gate and a circular driveway. Investigators also said they did not know whether this was a random home invasion or a targeted assault.

The assailant in the sketch released Saturday is described as a skinny Latino or white man, about 23 or 24 years old, about 6 feet tall, with black hair, dark eyes and a light complexion.

"Other subjects were also believed to be inside the victim's home at the time of occurrence, however how many others were involved and their descriptions are not known at this time," police said.

Anyone with information is asked to call Sgt. Mike D'Antonio at (408) 827-3219 or (408) 354-8600.
