NEW YORK (CBS 2) -- In Borough Park and surrounding neighborhoods where the Jewish Sabbath is strictly observed, there was silence on the street as Jewish congregations across the city reflected on the murder of 9-year-old Leiby Kletzky.
Kletsky family friend Yitzchok Spitzer said after a Sabbath spent with God, shiva resumes.
"Now after sabbath we're back down ourselves we have to resume crying," he said.
"We're really sad to know it happened within our community," said neighbor Michael Yusupov.
Just five days ago, Leiby got lost and, police say, asked the wrong man for directions. His body was found the next day, a discovery sending shock across the tight knit community, and the rest of the city.
Congressman Michael Grimm, whose Staten Island district also covers a part of Brooklyn, was an FBI agent. He told Guzman, "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."
Police think that is a possibility, and Levi Aron's defense lawyers have already prepared for an insanity defense.
"He's indicated to me that he hears voices. And there's some hallucinations involved as well," said defense lawyer Pierre Bazile.
The suspect has undergone psychiatric evaluation at Bellevue Hospital, but one investigator close to those who were in the room when Aron made his statements, his alleged confession, investigators with experience in insanity cases, said it appears to them that he was somewhat calm and rational in his own way when he made those statements.
In other words, a judge, they say, may find that Aron is fit to stand trial.
"It's nice to have a motive, and do I think I can develop a motive? Yeah I think so," said Brooklyn DA Charles Hynes.
In Kensington Aron's house, investigators for more than three days were looking for evidence.
"Certainly we knew people who were searching for him. And everybody was very affected. In fact, we had people come to temple who hadn't been to temple in a while 'cause they needed to hear this message. And it's hard," said Cantor Suzanne Bernstein of the Progressive Temple Beth Ahavath Sholom in Borough Park.
Investigators are fanning-out to where Levi Aron has lived in Tennessee as well as Little Rock, Arkansas and Florida. In all those places he either married or was engaged to single Jewish women.
According to sources in the Brooklyn District Attorney's Office, an indictment is expected to be handed up early next week.
A house three doors down from Aron's is where Zisa Berkowitz reportedly told neighbors and cops a chilling tale that her son may have been an earlier target.
No one answered Saturday at the Berkowitz home, but family friend Dalia Kessler was familiar with the incident.
"He was calling him to come up to his house. The boy said 'I have to ask my mom.' He ran home," she said.
