Marin murder suspect extradited from Idaho

Marin County authorities have extradited an Idaho resident charged with the 1973 murder of a San Rafael woman.

According to the district attorney's office, Michael Eugene Mullen, 75, is scheduled to make his first appearance in Marin County Superior Court on Monday.

The victim, 31-year-old Nina Fischer, was found tied up and shot to death in her family's home on Point San Pedro Road. The case remained unsolved for decades, but investigators arrested Mullen in August after DNA evidence linked him to the crime, the Marin County Sheriff's Office said. Mullen formerly lived in Sonoma County.

Mullen was held in an Idaho prison pending his extradition and Marin County authorities took him into custody on Thursday.
