Verdict in a Decades-Old Marin Case
After days of testimony in a San Rafael courtroom, a Marin County jury found Michael Eugene Mullen, then 77, guilty of first-degree murder in connection with Nina Fischer’s slaying. The verdict marks a turning point for residents of towns from Sausalito to Corte Madera who have long wondered who harmed Fischer in her home on Point San Pedro Road.

Investigators determined Fischer had been bound, shot, and subjected to sexual assault and violence with a wine bottle. The court set sentencing for June 10, with Mullen facing a possible life sentence in a case that stretched from Marin’s coastal towns to the inner neighborhoods of San Rafael and Novato.
