A lawyer for a man suspected of killing a reputed New York mob boss says hate speech and right-wing conspiracy websites are to blame for recent changes in the man�s behavior.

However, Anthony Comello pleaded not guilty on Monday as he was arraigned under heavy security on murder and other charges in the March 13 killing of reputed Gambino boss Francesco �Franky Boy� Cali.

Authorities say the Staten Island slaying may have been related to a romantic dispute, not mob business.

At a court appearance last week, the 24-year-old had pro-Donald Trump slogans and an apparent conspiracy symbol on his hand.

Attorney Robert Gottlieb said Monday Comello�s family attributes behavior changes to �hate spewed throughout the internet.�

He�s being held without bail. His next hearing is April 3.
