MONTE SERENO -- Police handling the case for the killing of Silicon Valley venture capitalist Raveesh "Ravi" Kumra refused to provide any further information Sunday, a day after announcing they had arrested three more suspects.

Kumra, a tech investor who once owned the Mountain Winery in Saratoga, was killed in his 7,000-square-foot Monte Sereno home on Nov. 30 at age 66, the first homicide in the small town since 1972. His wife, Harinder, called 911 after being beaten by the suspects, who also ransacked the home, police said.

Since then, Los Gatos-Monte Sereno police have arrested a woman with a history of prostitution, Raven Chanel Dixon, 22, of Alameda, who was arraigned on Dec. 21 after being charged as an accessory in the killing.

On Saturday, police issued a short news release announcing they had arrested three more suspects on suspicion of homicide: Lucas Anderson, Javier Garcia and Deangelo Austin. Anderson appeared in court Friday while Garcia and Austin could be arraigned as soon as Monday.

Austin was booked by police in Sacramento on Saturday, Garcia was arrested by Oakland police Thursday and Anderson was charged after being interviewed on Wednesday in Santa Clara County Jail, where he was in custody on unrelated charges.

No further details have been released. Still publicly unknown are:

  • How Kumra died, or whether weapons were used in his death

  • How the suspects were connected to one another and the victim

  • The ages and hometowns of Anderson, Garcia and Austin

  • The motive in the killing

  • Whether there are more suspects (Harinder Kumra originally told police there may have been three or four suspects)

    More information could be released Monday.

    Sgt. Kelly Harris, a spokesman for the police department, said additional details have not been provided due to what he termed the "active and ongoing" investigation. He did not know whether the three latest suspects have hired lawyers.

    The Santa Clara County District Attorney's Office, contacted on Sunday, also did not have further information on the case.
