A garment salesman accused of being a serial killer of Brooklyn shopkeepers has been found mentally fit for court.

The Daily News says a Brooklyn judge discussed doctors' finding Friday in Salvatore Perrone's case.

They determined Perrone doesn't suffer from hallucinations or delusional thinking and understands the charges against him.

Perrone has behaved oddly at court appearances. Authorities say he told detectives he was working with what he termed "the Palestinian section of the CIA."

But the judge says doctors concluded his remarks reflect a personality disorder, rather than a mental illness that would legally disqualify him from standing trial.

The 64-year-old Perrone is accused of shooting three merchants to death as they worked alone in their clothing stores last year. He has pleaded not guilty.
