The attorney for Hans Reiser argued Monday the prosecution in his client's murder case has failed to prove Reiser killed his estranged wife — if she is even dead at all.

During his third day of closing arguments, William DuBois again told the jury that the software engineer's odd behavior after his wife went missing does not prove guilt because he is an "eccentric intellect."

DuBois told the jury how his client is not normal, and his strange behavior — such as not looking for his wife or ripping the passenger seat out of his car — does not illustrate his guilt, but rather his eccentricities.

"I've stipulated he's not normal," DuBois said. He then turned to his client and said, "Sorry, Hans, you're not normal."

DuBois said all the jury needs to do is look at the video of him explaining his computer file system at a seminar at Google to see he is a "genuine nerd" and not like most other people.

DuBois added his strange behavior "is not because he is hiding evidence, but because he is strange."

However, DuBois added if jurors do find his client guilty, they should convict him of voluntary manslaughter — not the more serious charge of murder — because the crime would have been done in the "heat of passion."

Nevertheless, DuBois' main point was that the prosecution has not proven beyond a reasonable doubt its case against Reiser.
