MEEKS BAY -- A San Ramon husband and wife are dead after their boat crashed into a dock Sunday night at Lake Tahoe, authorities said.

The victims have been identified as Tatiana Nikolskaya, 44 and her husband 45-year-old Vadim Raizanov, who ran a psychiatry practice in San Ramon.

The couple's 19-foot boat was traveling at a high rate of speed when it hit a pier piling and the hull of the boat split in half. Officials say the force of the collision woke up people who had been sleeping on the dock at the time.

Firefighters and deputies pronounced the couple dead at the scene. Authorities are looking into the possibility that alcohol was involved.
