the Etan Patz case wraps up Thursday, and on Tuesday, the jury is expected to start digging through the mountain evidence to decide whether Pedro Hernandez killed the 6-year-old boy all those years ago. NY1's Michael Herzenberg filed the following report.

Pedro Hernandez confessed on video four times to strangling Etan Patz in 1979, even showing police where he dumped the boy in an alley like trash.

Prosecutors also used video of Hernandez at his daughter's sweet sixteen and other home movies arguing that he does not have a serious mental illness.

They also called three people who testified that Hernandez tearfully confessed to them at a religious retreat just months after Etan vanished. Two of them said Hernandez admitted he lured a boy to the basement of the SoHo bodega where he worked and cut him into pieces.

A fourth witness, a former neighbor, said Hernandez told him a slightly different story, that a "...young male threw a ball at his store...he strangled him...he put him in a bag and then a nearby alley."

Then, there's the ex-wife. She testified that in 1982, before they got married, Hernandez confessed that he felt violated by a "young man," so he strangled him. She said she found a piece of a missing poster of Etan in Hernandez's shoebox.

However, the defense team says Hernandez made up all these stories and believed them.  

"There is no evidence against Pedro Hernandez other than his words, which are totally unreliable," said defense attorney Harvey Fishbein. 

The defense actually introduced those home movies to show Hernandez's social isolation. 

Their expert psychiatrist testified that Hernandez is mentally ill and "completely unclear as to what's real and what's not."

More than any expert, though, the defense case might hinge on convicted pedophile Jose Ramos, who dated a woman who walked Etan home from school.

The FBI investigated Ramos for more than a decade. One federal prosecutor testified that Ramos admitted being 90 percent sure he tried to molest Etan, but was rebuffed, and put the boy on the subway the day Etan disappeared.

There was never enough evidence to charge Ramos, but the question is whether that evidence will be enough to raise enough doubt that Pedro Hernandez killed Etan Patz.
