Marshall McMains Goldberg, 55, allegedly kidnapped his 85-year-old mother, Doris Goldberg, from her home in Ashland, Ore., where she was living with another son on May 24, FBI San Francisco Division spokeswoman Julianne Sohn said.
Doris Goldberg, who suffers from Alzheimer's disease and dementia, is considered "endangered" because she is unable to care for herself.
On May 31, a Jackson County, Ore. grand jury indicted Marshall Goldberg on state charges of kidnapping, custodial interference and contempt of court. Local authorities believe that he fled the state with his mother, and obtained a federal fugitive warrant on June 30.
Marshall Goldberg has ties to Daly City and the Bay Area, where the FBI suspects he initially traveled after the kidnapping, FBI Portland Division spokeswoman Beth Anne Steele said.
"He has known acquaintances in the Bay Area," Steele said.
Marshall Goldberg has connections to Los Angeles and its North Hollywood district, Steele said. He previously worked as an unskilled laborer in the film industry and may try to do so again, she said.
He is described as a white man standing 5 feet 9 inches tall, weighing between 160 and 165 pounds, who has brown hair and blue eyes and may wear glasses.
Doris Goldberg is described as a white woman standing 5 feet 1 inch tall, weighing about 135 pounds, with white hair and blue eyes.
The FBI suspects Marshall Goldberg may be driving a 1996 gold Oldsmobile four-door sedan with the California license plate 3SZY023.
Anyone with information about Marshall or Doris Goldberg's whereabouts is urged to call the FBI San Francisco Division tip line at (415) 553-7400.
