Pedro Hernandez watched 6-year-old Etan Patz from the corner store where he worked all those years ago, prosecutors said. He knew the little boy liked to get treats there, and that he waited for the school bus in the morning without adult supervision, they said.

He was โ€œkeenly watching and admiring this beautiful friendly child,โ€ Manhattan Assistant District Attorney Joan Illuzzi said during summations Tuesday in Hernandezโ€™s retrial. Prosecutors say the 56-year-old Maple Shade, N.J., man lured the little boy into the basement with the promise of a soda on May 25, 1979, then choked him and dumped the body.

Etanโ€™s body was never found, but his case helped usher in an era of vigilance. The anniversary of Etanโ€™s disappearance became National Missing Childrenโ€™s Day. His parents helped press for new laws that established a national hotline and made it easier for law enforcement agencies to share information about missing children.

Hernandez gave a surprise confession in 2012, after the case made national news again when federal agents dug up a New York City basement looking for Etanโ€™s remains. He was tried once before, but the case ended in a hung jury after all but one juror voted to convict after 18 days of deliberations.

The probe had long focused on another suspect, convicted pedophile Jose Ramos. Hernandezโ€™s attorney Harvey Fishbein said during his closing argument Monday that Ramos was the real killer. Ramos has said he didnโ€™t kill the boy.

Over the years, Hernandez told a friend, his ex-wife and a church group that he had killed a young person in New York by choking and dumping the body, though the details varied, according to trial testimony. He never mentioned Etan by name, but his brother-in-law called police with the tip that led law enforcement to him.

Those statements to others, the fact that he was a 19-year-old stock boy nearby when Etan vanished and his believable confession are enough to convict, Illuzzi said.
