A panel of the 4th District Court of Appeal overturned the conviction of Anthony Ferrari, finding, in part, that investigators had not obtained a warrant before obtaining past information about cell-phone locations.

The ruling came after the appeals court in June ordered a new trial for Anthony “Big Tony” Moscatiello, who also was alleged to have been part of a plot to kill businessman Gus Boulis in Broward County.

Boulis’ murder came amid a dispute about SunCruz Casinos, which he had owned.

Ferrari and Moscatiello were reputed to have ties to the Gambino crime family.

Ferrari was convicted of first-degree murder and conspiracy to commit first-degree murder. But in a 21-page ruling Wednesday, the appeals court ordered a new trial because of two issues, including a finding that a circuit judge improperly denied a motion by Ferrari to suppress “historical cell-site location information.”

The ruling said investigators obtained data on two of Ferrari’s cell phones that showed their location on the night of the murder. But it pointed to a U.S. Supreme Court ruling this year that said obtaining such “historical” data requires a search warrant.

“The acquisition of this data without a warrant based on probable cause constituted an illegal search pursuant to the Fourth Amendment,” said the ruling, written by appeals-court Judge Martha Warner and joined by judges Robert Gross and Carole Taylor.
