32-year-old Katrina Fritz was arraigned on murder and robbery charges in San Jose Friday. Her exact involvement remains a secret because court documents were not made public.
Ravi Kumra was murdered last November at his estate in Monte Sereno. He apparently suffocated from the duct tape he was tied up with.
Three men and another woman have also been charged in Kumra's death.
They are expected to appear in court next month.
