The murder trial against Hans Reiser starts on Monday. Even without a body, prosecutors say they have a solid case. Reiser, a prominent and successful East Bay computer programmer, is accused of killing his wife Nina a year ago. ABC’s 20/20 got an exclusive interview with him. It’s been little more than a year since Hans Reiser was arrested and charged with the murder of his estranged wife. A jury was finally selected last week after going through a pool of 300 people.
