Investigators have arrested an Idaho resident on suspicion of murdering a San Rafael woman in 1973, the Marin County Sheriff’s Office announced Thursday.
Michael Eugene Mullen, 75, was linked by DNA evidence to the case of Nina Fischer, who was slain at her home on Point San Pedro Road. Fischer was 31 years old.
Authorities booked Mullen into the Lemhi County jail in Idaho, where he awaits court proceedings for an extradition to California.
The victim’s husband, Gunnar Fischer, found her body after coming home in the evening from his office in San Francisco, authorities reported at the time. She had been bound, gagged and shot twice.
Investigators found no sign of forced entry into the home. The Fischers’ 2-year-old daughter was found unharmed and napping in another room.
