In her third day on the witness stand in Hans Reiser's trial on charges that he murdered Nina, who was last seen alive on Sept. 3, 2006, social services investigator Seng Fong said there are concerns about 8-year-old Rory Reiser's mental health status, according to attorneys for Irina Sharanova, Nina's mother.
Sharanova has custody of the Reisers' two children, Rory and his sister Nio, and is raising them in St. Petersburg, Russia, which is where Nina lived before she married Hans and came to the U.S.
Nina Reiser's body has never been found, despite extensive searches in the Oakland hills and elsewhere, but prosecutors charged Hans Reiser with murdering her because they believe that DNA and blood evidence proves that he killed her.
The couple married in 1999 but Nina filed for divorce and separated from Hans in 2004. They were in the midst of an acrimonious divorce and a battle over the custody of their children when she disappeared.
Hans Reiser has pleaded not guilty to the charges against him.
DuBois has said he thinks that Nina Reiser may still be alive and be in hiding in Russia, where she was raised and where she was trained as a physician.
Sharanova is expected to testify next week.
