Levi Aron is accused of kidnapping and murdering 8 year-old Leiby Kletzky. On Thursday he pleaded not guilty to second-degree murder and kidnapping charges, according to NBC News.
A first-degree murder indictment of Aron could come as early as today, CBS News reports.
Aron told his lawyer that he suffers hallucinations and hears voices, according to the New York Times, and the judge has ordered Aron be held without bail while he undergoes a psychological evaluation and is put on suicide watch.
Aron apparently has already confessed to the murder, according to police.
In the meantime, a portrait of Aron as a lonely, distraught man has emerged. The New York Daily News and The New York Post tracked down Aron's two ex-wives, both single moms he met online and to whom he was married less than a year.
It's not clear how Aron, 35, met wife No. 1, an Israeli named Diana Diunov, who came to the U.S. in 2002 for a liver transplant with her daughter, Edita.
They married in June 2004. Seven months later, Diunov was indicted in Manhattan Federal Court for bilking diamond supply companies of $1.7 million.
Aron and Diunov split in August 2005; less than a month later, she married Boris Shvartzman, her co-conspirator in the diamond scam. She's in prison.
Aron moved on quickly, however, marrying Debby Kivel, a Memphis mom of two, just seven months after his divorce was final. The couple met on the Jewish matchmaking site, sawyouatsinai.com, and Aron moved in with her and her two young children.
Kivel dumped Aron a little less than a year later and the Post obtained a protective order she filed in 2006 claiming Aron was phycially abusive.
In one instance, months after their separation, the court document claims Aron snuck into Kivel's bedroom while she was sleeping and asked her to have sex with him, the Post reports. The document says Aron had previously called her and "if she did not have sexual relations with him, then he would kill himself, period."
The order also claims Aron had "been diagnosed with a behavior disorder and takes medication for the condition."
And disturbingly, considering the grisly details of Leiby Kletky's murder, Aron was a butcher during his time in Tennessee. A member of the synagogue where Aron and Kivel got married told the Post, "People complained because he sliced the meat so slowly, so methodically, and some realized he wasn't 100 percent."
After Tennessee, Aron moved back to his parent's attic in Brooklyn where he continued to pursue women online, in one instance getting engaged to a woman in Florida, who broke off the relationship weeks before the wedding, the News reports.
Yesterday thousands turned out to mourn the loss of Lieby Kletsky, as a neighborhood is left shocked and heartbroken over the news. "It's as if we all lost a child," said one woman.
