Three boxes of evidence from the investigation into Etan Patz's disappearance have turned up at a Harlem police station.
An attorney for Pedro Hernandez, the man accused of killing the 6-year-old decades ago, said because of the discovery, the defense may seek a mistrial or recall witnesses who already testified.
The information came out the same day jurors heard more testimony from an NYPD detective who interviewed Hernandez in New Jersey in 2012.
During the interrogation, the detective said Hernandez told detectives, "I'm sorry. It shouldn't have happened. I choked him. I saw him standing in front of the store on the corner. I asked him if he wanted a soda. He said, 'Yeah.' I told him, 'Go to the basement.' I don't know why I did it."
The defense has pointed out that the confession came after several hours of untaped interrogation.
They also argue that the confession means nothing because Hernandez suffers from mental illness and has a low IQ.
"At a minimum, what it shows is that the historical file is incomplete. They just found three new boxes and the fact that they don't have all the records from 1979 will become very relevant at another point in this case," said Harvey Fishbein, Hernandez's attorney.
Patz disappeared while walking to school in SoHo in 1979.
