Police May Have Cracked 33-Year-Old Etan Patz Case AP / Ron Frehm / File Stan Patz, left, with other son Ari, holds a photo of his son Etan. (NEW YORK) - A man has implicated himself in the death of 6-year-old Etan Patz, whose disappearance 33 years ago on his way to school helped launch a missing children's movement that put kids" faces on milk cartons, police said Thursday. Investigators were still going over details of the man's story. The development came just before the Friday anniversary of the boy's disappearance, when detectives traditionally receive a landslide of hoaxes and false leads related to the case.

The law enforcement official said the man has been tied to the case in the past. "An individual now in custody has made statements to NYPD detectives implicating himself in the disappearance and death of Etan Patz 33 years ago," Police Commissioner Raymond Kelly said in a statement. Kelly said he expected to release additional details later Thursday. The man's emergence as a person of interest was not related to the search of a Manhattan basement in April, according to a person familiar with the investigation. Both the person familiar with the probe and the official spoke to The Associated Press on condition of anonymity because they weren't authorized to discuss the ongoing probe into the boy's disappearance in 1979.

He had been known to detectives for years, but it was unclear what brought them back to him this week. Wearing a backpack, the boy with sandy hair and a toothy grin vanished May 25, 1979, while walking alone to his school bus stop for the first time, two blocks from his home in New York's SoHo neighborhood. There was an exhaustive search by the police and a crush of media attention. The boy's photo was one of the first of a missing child on a milk carton. Thousands of fliers were plastered around the city, buildings canvassed, hundreds of people interviewed. Etan's parents, Stan and Julie Patz, were reluctant to move or even change their phone number in case their son tried to reach out. They still live in the same apartment, down the street from the building that was examined in April. They have endured decades of false leads, and a lack of hard evidence.

The Patz family did not immediately return a message requesting comment. Etan's disappearance touched off a massive search that has ebbed and flowed over the years. It also ushered in an era of anxiety about leaving children unsupervised. In 2010, Manhattan District Attorney Cyrus R. Vance Jr. announced he was reinvestigating what is still considered a missing persons case. In the past, the case seemed to have been largely focused on Jose Ramos, a convicted child molester, now serving time in Pennsylvania, who had been dating Etan's babysitter at the time the boy disappeared. In 2000, authorities dug up Ramos" former basement on the Lower East Side of Manhattan, but nothing turned up.

A civil judge in 2004 found him to be responsible for Etan's death. More recently, the focus had shifted to a 75-year-old Brooklyn resident, though he was not named a suspect and denied any involvement. In 1979, he was a handyman who had a workspace in the basement where the April excavation occurred. The handyman's lawyer, who has maintained his client was not involved in the crime, said he would speak with his client and release a statement later.
