OAKLAND, Calif. -- Few people outside of an Oakland courtroom have seen the evidence that led a jury to convict Hans Reiser of murdering his wife Nina despite the fact that her body has never been found. KTVU takes an exclusive first look at the pieces of the puzzle that cracked the Reiser case.

The Alameda County District Attorney's office shared with the KTVU Channel 2 News pieces of evidence that have only been seen publicly inside the courtroom during Hans Reiser's murder trial.

Prosecutor Paul Hora gave KTVU access to two large binders containing hundreds of pictures that help illustrate the anatomy of a murder.

For the first time, we see photos of the car Reiser was driving and the mysteriously missing front seat. In addition, Hora showed blood belonging to Nina found on an item in the trunk of the car.

"The sleeping bag stuff sack had blood on it," explained Hora.

It was September 3rd, 2006, when 31-year-old Nina Reiser vanished after bringing her two young children to her husband's home. Oakland police began an extensive search for the missing woman, combing thru Hans' home where investigators say Nina was last seen alive.

They say her blood was on this post near the front door. 9 days after she vanished, Hans was driving his mother's Honda CRX when a police officer pulled him over in Redwood City for a traffic violation.

The officer said the front passenger seat was in the car at that time. Less than a week later, Oakland police closed in on Hans Reiser.

"They had an airplane and twelve police officers in several different cars following him and that day, the defendant led police to this CRX," said Hora.

That was when officers found the front passenger seat missing. And that wasn’t all that had disappeared from the vehicle.

"[In] the trunk where the spare tire was, the cover that went over the spare tire and the entire carpeting over the trunk area was missing. All gone. He also discarded that. Basically three-fourths of the car was gone," recalled Hora.

Investigators also found Nina's van three miles from Han's home. In it were her purse and groceries from the Berkeley Bowl supermarket bought the same day she disappeared.

Hora says Nina was not planning on going away.

"It was September 3rd. She had just made out her rent check and was getting ready to drop it off at her landlord's house," said Hora.

And Nina's use of her cell phone ceased that same day.

"In the end, the evidence just keeps building and building. It gets to the point that the only reasonable conclusion is she's dead, and that replaces having a dead body," explained Hora.

Hora used a jigsaw puzzle to demonstrate to jurors how authorities pieced together the case and solved the crime.

Still, mysteries in the case remain. Reiser’s conviction doesn't answer the question of how he killed his estranged wife Nina or where he hid the body.

But nonetheless, the prosecutor says there was enough evidence to for the jury to conclude Reiser’s guilt beyond a reasonable doubt.
