Following Levi Aron's arraignment yesterday for the murder and dismemberment of 8-year-old Leiby Kletzky, authorities are still attempting to piece together the profile of a man who would commit such atrocities. As the Times reports, though he was a regular at karaoke bars on Long Island, the people who frequented the events said "Aron did not mingle much with others." In addition to performing in bars, Aron, who reportedly had dreams of being a contestant on American Idol, also sung covers on the website SingSnap.com.

While someone has deleted Aron's profile and solo tracks, the Daily News located several duets that he performed with other singers over the internet, including the Cher/Peter Cetera duet "After All," Evanescence's "Bring Me to Life," and the Maroon 5/Rihanna song "If I Never See Your Face Again." The latter features "LeviA's" unsure, expressionless voice singing the lyrics, you feel my breath on your neck / can't believe I'm right behind you. Another user who unwittingly performed a duet with the 35-year-old hardware store clerk told the paper, "This puts chills up my spine." Listen to Aron's version of "If I Never See Your Face Again" that he sung with "m32" below.
