BOROUGH PARK - The lawyer of a Brooklyn man accused of kidnapping and dismembering an 8-year-old boy who asked him for directions says that his client is not fit to stand trial.

Levi Aron's lawyer says his client also told him that he has had hallucinations and hears voices. Aron is undergoing a psychiatric evaluation.

Meanwhile, authorities continue their investigation this morning, removing bags of evidence from inside Aron's residence. Detectives had also been examining three computers seized from Aron's home since his arrest.

Brooklyn district attorney Charles Haynes says investigators are looking at whether Aron had improper contact with children in the past.

Investigators confirmed yesterday that Leiby Kletzky was smothered or suffocated to death. So far, there are no signs of sexual molestation.

Police also revealed that Kletzky may have tried to fight back against Aron, before he was killed. They say Aron has scratches on his arms and wrists that show signs of a possible struggle.

Police Commissioner Raymond Kelly confirmed that Aron gave a written statement saying that he is sorry for hurt that he caused. Kelly went on to say that other than that, "He hasn't expressed any remorse."
