His dismembered body was found in the Kensington apartment of Levi Aron, aged 35, and in a dumpster in another Brooklyn neighborhood, Greenwood Heights, on Wednesday morning July 13.

The dentist's reception records led police to Aron at his apartment, where he showed them parts of the boy – and told them where he had dumped the rest of the body.

The case drew comparisons to the 1979 kidnapping of six-year-old Etan Patz from nearby SoHo, who was abducted while walking to his school bus for the first time.

[3][5] He was reported missing late Monday afternoon while walking home from a day camp held at his school, Yeshiva Boyan Tiferes Mordechai Shlomo.

[3] It was the first time that his parents allowed him to walk alone and they had practiced the route the day before; his mother waited for him at a predetermined point a few blocks away at 50th Street and 13th Avenue.

[13] State Assemblyman Dov Hikind posted a $5,000 reward for information leading to the return of the child, which was eventually upped to $100,000 by members of the community.

[7][9] Meanwhile, Yaakov German, a Bobover Hasid and father of Kletzky's yeshiva rebbi,[5] went door-to-door on Tuesday morning with his son to examine videos from surveillance cameras posted in stores and offices along the boy's route.

[5] After examining the videos, police located the dentist, who alerted his receptionist, the wife of community political operative Simcha Eichenstein.

[16] Forty-five minutes later,[16] two Flatbush volunteers searching for the missing boy in Kensington spotted the car and sent in the license plate number, which matched Aron's details.

[9][17] They arrived to an open door, and when they asked Aron where the boy was, he allegedly nodded toward the kitchen, where the police found blood-soaked carving knives and bloody towels in bags.

[18] The suspect told police where to find the rest of the remains: in a red suitcase[19] thrown in a dumpster on 20th Street between Fourth and Fifth Avenues.

[9] According to a 450-word handwritten statement in which he confessed to killing the boy, Aron claimed that Kletzky had asked him for directions and accepted a ride, saying he wanted to be dropped off at a bookstore.

[29] In December 2011, another of Aron's attorneys, Howard Greenberg, sparked outrage when he remarked of his client, "Look, everybody knows when blood relations have offspring, there can be genetic defects...

[25] On July 20, 2011, the office of the New York City medical examiner released autopsy results revealing that Kletzky had ingested a lethal mix of four different drugs and had then been smothered.

The cause of death was determined to be intoxication from a combination of cyclobenzaprine (a muscle relaxant), quetiapine (an antipsychotic), and hydrocodone and acetaminophen (two analgesics), followed by smothering.

[31] On August 9, 2011, the New York City medical examiner's office revealed that Kletzky had ingested a fifth drug, Duloxetine, which is used for generalized anxiety disorder and as an antidepressant.

Rendelman was the attorney who successfully prosecuted Horace Moore for the stabbing murder of NYC bus driver Edwin Thomas.

[48][49] In November 2011, the Appellate Division of the State Supreme Court denied Aron's counsel's request to move the trial to Suffolk County or The Bronx in light of unfavorable media coverage in Brooklyn.

[53] On August 1, 2012, it was reported that prosecutors had struck a deal with the defense in which Aron would plead guilty in exchange for a sentence of at least 40 years to life in prison.

On August 17, 2011, Nachman Kletzky filed a $100 million civil lawsuit against Aron in Brooklyn Supreme Court, seeking damages for the "abduction, kidnapping, torture, murder and dismemberment" of his son.

On August 23, Kletzky filed a $100 million civil suit against Aron's father, Jack, for neglecting to monitor his son or protect Leiby while the latter was in his home.

[61] New York City Councilman David Greenfield has said he would propose "Leiby's Law," a bill under which businesses could volunteer to be designated as safe places for children who are lost or otherwise in trouble.

Employees would undergo background checks and business owners would put a green sticker in their store windows so children know it is a safe place to get help.

[67] In early August, Hasidic singer Lipa Schmeltzer released a ballad called "Leiby Forever" and a seven-minute music video showing home movies of Kletzky growing up.
