The opening as it read in 2015
On July 11, 2011, Leiby Kletzky , a Hasidic Jewish boy, was kidnapped as he walked home from his school day camp in the mainly Hasidic neighborhood of Boro Park , Brooklyn in New York City , New York . His dismembered body was found in the Kensington apartment of confessed murderer Levi Aron, aged 35, and in a dumpster in another Brooklyn neighborhood, Greenwood Heights , on Wednesday morning July 13. Kletzky's disappearance sparked an all-out search by New York City police and a block-by-block search by up to 5,000 Orthodox Jewish volunteers from New York and other states coordinated by the Brooklyn South Shomrim volunteer civilian patrol. – July 12, 2011 Aron was apprehended early Wednesday morning after examination of videos from surveillance cameras along the boy's route showed him meeting a man outside a dentist's office and then apparently getting into his car. Aron gave a 450-word handwritten confession to police after his arrest, but pleaded not guilty at his first court hearing. The kidnapping and murder of the eight-year-old boy shocked the insular Brooklyn Hasidic community, whose streets are considered relatively safe.1The case has drawn comparisons to the 1979 kidnapping and murder of Etan Patz , a six-year-old SoHo resident who was snatched while walking to his school bus for the first time.2 Before the case went to trial, on August 9, 2012 Aron pleaded guilty to one charge of second-degree murder and one charge of second-degree kidnapping as part of a plea bargain agreement worked out between prosecutors and defense attorneys. On August 29, Judge Neil Firetog sentenced Aron to 40 years to life in prison. Aron would be eligible for parole in 2051, which includes credit for time served.
