Levi Aron was arrested on Wednesday and charged with second-degree murder. He is accused of snatching Leibby Kletzky off the street and taking him to his home, where police say he suffocated and dismembered him.

“I understand this may be wrong and I’m sorry for the hurt that I have caused,” Aron wrote in a confession exclusively obtained by NBC New York.

Police Commissioner Ray Kelly said ahead of the arraignment today that Aron has shown “no remorse,” at times giggling when speaking with investigators.
