According to several news sites, Hans Reiser was arrested earlier today on suspicion for the murder of his wife Nina Reiser. His wife has been missing since September 3. The police have been quoted as saying "biological evidence that puts the missing woman in a car her husband had access to is a strong part of the circumstantial case against him. They would not say what the biological evidence is, but the term usually includes blood, hair or other body fluids." Apparently Nina Reiser's friends "have told authorities she would never had voluntarily ridden in a car with him.""
