Accused child killer Levi Aron told police in his initial confession that he gave 8-year old Leiby Kletzky a tunafish sandwich - but he did not mention the potent drug cocktail of anti-psychotics, painkillers, and muscle relaxers that police now believe was sprinkled on the sandwich.
New York City medical examiner said that Leibby Kletzky died of acute intoxication. The autospy also indicates that he was smothered, as Levi Aron admited in his confession.
Aron's confession was one-part candid, one-part mystifying in that he was willing - even eager - to provide investigators with graphic details of certain aspects of the kidnapping and murder, but other aspects of his confession did not add up.
For example, Aron told police that he brought the boy to a wedding in upstate New York, but when the bride and groom were questioned, neither could recall seeing the boy there. This was one reason police believed that Leiby had been killed on Monday, July 11 instead of Tuesday, as Aron claimed.
It turns out that Leiby did in fact accompany Aron on the ride to the wedding, but remained in the car during the event.
Security cameras at a Sunoco gas station on the Palisades Parkway in New Jersey caught what are believed to be the last images of Leiby Kletzky alive.
A station attendant who saw the tape told the Daily News, It made me so sad. ... The kid didn't look nervous. He wasn't looking around. He just walked in front of [Aron].
Levi Aron, 35, was indicated Wednesday on two counts of first-degree murder, kidnapping, and additional charges.
There was an intent to kill, and that's based on the ingestion of the medication, Brooklyn DA Charles Hynes told the New York Post.
While there is no comfort to be found in any developments in the boy's shocking death, the possibility that he was unconscious before he was smothered, and was certainly dead before he was dismembered, can be seen as lesser evil than speculation last week that he may have been alert.
However, police have found evidence that Lieby was restrained for up to 12 hours, presumably when Aron went to work on Tuesday, which would explain why the child did not flee the apartment.
The boy had marks on his wrist that indicated at one point he was tied up, Hynes said, adding that there was no evidence of sexual abuse.
Leiby Kletzky was given permission from his parents for the very first time to walk part of the way home from Boyan Day Camp on 44th Street and 12th Avenue in Borough Park, Brooklyn. Leiby and his parents had practiced the route the day before, and had a prearranged meeting point a short distance from the camp.
At some point during the walk, Leiby went off course, and may have asked Levi Aron for directions. Surveillance video shows Leibby conversing with Aron, who was seen leaving a dentist's office.
Police later tracked down the dentist at his home in New Jersey, and office records provided enough information that they were able to locate Aron at his Kensington apartment - which is about a mile from the home of Leibby's parents and three sisters.
Levi Aron made no attempt to deny his involvement with Leibby's death, pointing police in the direction of the boy's remains when they first apprehended him at his apartment.
Aron provided a detailed confession after being taken to police headquarters. Aron indicated that he did not initially intend to kill the boy, claiming that he panicked after realizing the massive scale of the search effort for him. Although Aron's confession had previously come under scrutiny, the discovery of drugs in Leiby's system are evidence that the killing was premeditated, ruling out any possibility that he could qualify for a lesser, second-degree charge.
The prescription drugs - which included the schizophrenia drug quetiapine - belonged to Aron, which could impact his defense's claim that Levi is mentally unstable.
