Over the weekend, investigators continued to scour the 35-year-old's home in Kensington, Brooklyn, taking dozens of pieces of new evidence, including pieces of furniture and his car.

Using Aron's DNA, police were investigating whether he may be connected to any other cases of child abuse -- or worse. Investigators are fanning out to Tennessee, Arkansas and Florida. In all those places he either married or was engaged to single Jewish women. "We're gathering as much forensic evidence as we can," Brooklyn District Attorney Charles Hynes said. Hynes said that the evidence that was being taken from Levi Aron's house will be part of the murder indictment against him, which will be unsealed this week. "We will ask for the main charge of felony murder, based on the kidnapping, which is murder in the first degree," Hynes said. Police said Leiby Kletzky got lost when leaving day camp, and asked the wrong man for directions. Kletzky was killed and his dismembered body was found in two different Brooklyn locations. Congressman Michael Grimm, whose Staten Island district also covers a part of Brooklyn, was an FBI agent. "The very first thing that crossed my mind is that we had a psychopath on our hands. And that there could possibly be, more bodies out there," Grimm told CBS 2′s Pablo Guzman. Aron has been undergoing psychiatric evaluation at Bellevue Hospital and its said his attorneys are considering an insanity defense. Yosef Moskowitz knew Aron growing up and says he also seemed normal, but that as he got older, he seemed to grow socially awkward. "He needed help. He really needed psychiatric help. And somewhere along the line, people, the family maybe missed it," he said. This week will also mark the end of the shiva which Leiby's family has been sitting for the last seven days. Family and friends have been coming by their apartment, trying to comfort them. They also want to provide them with a sense of strength to get through what could be a difficult few weeks as details emerge about what happened to their son. "God should give them relief and hopefully that they should be able to continue in life and raise the rest of their family and participate in their happiness and their joy and happy times together," said Yosroel Friedman, Kletzy family friend. If Levi Aron is convicted, what would the appropriate punsihment in this case? Prison, therapy or something else? Sound off in our comments section.
