NEW YORK (PIX11) -- The Manhattan's DA's office says Pedro Hernandez  is responsible for the 1979 disappearance and murder of Etan Patz.

Hernandez appeared in a 7th Floor courtroom at 111 Centre Street Monday, along with a throng of media and the parents of Patz.

Patz was 6-years-old when he disappeared two blocks from his home on Prince Street as he walked to school for the very first time.

On Monday, prosecutors played out his dramatic videotape confession to Patz's murder from May 24, 2012.

Patz's mother, Julie Patz, left the courtroom before the video played while Hernandez sat stone-faced.

On video, a calm Hernandez says, "I felt like something took over me."

He describes strangling the boy seconds after luring him to the basement of a bodega: "I wanted to let go, but I couldn't let go."

He then tells investigators how Patz didn't die in his presence. "He went down to the floor again gasping ... Even though he was still alive, I put him in a plastic bag."

He says he then put the boy in a banana box and dumped him with pile of garbage in an alley on Thompson Street.

Also on the video, Hernandez tells authorities that he has a bipolar condition and takes a number of medications, which Harvey Fishbein, Hernandez's attorney touched upon during a break.

Hernandez has a psychiatric history and has been under psychiatric medicine for a number of years.

Fishbein also adds that his client was not truly cognizant of what was going on as a result of his mental limitations.

He's been tested thee times over the years and has an IQ of about 70.

The video is being played for both sides to make their case as to whether or not it will be allowed during trial.

It's ultimately up to the judge to decide whether the video will be admitted.
