A federal judge has thrown out part of the case against a former Long Island man accused of threatening four federal judges after he had already served 28 months in prison for threatening the lives of more than 40 financial regulators.

U.S. District Judge Denis Hurley ruled Monday that the government had not provided required statements from the judges as to how the supposed threatening letters or emails from Vincent McCrudden had affected them.

"ased on the limited record before me, I conclude that the government has not established that the defendant has violated either charge 1 or charge 2," Hurley wrote.

The tossed charges were attempting to influence a U.S. district judge or magistrate by transmitting threatening communications, and mailing threatening communications in violation of federal law.

But Hurley added in the summary that: "Indeed, but for the absence of reaction testimony from the recipients of McCrudden's letters and emails, several in all probability would have been found to be criminal in nature as alleged and, thus, violative of his supervised release."

Hurley also wrote that "there are numerous reasons to believe that McCrudden is a potentially dangerous individual" and "that he is in the early stages of the same course of escalating conduct that led to his underlying conviction."

McCrudden, 53, of Long Island City, Queens, had lived in Long Beach and Dix Hills.

He testified in November that his language to the judges may have been over the top, but he wanted to engage in nonviolent actions such as picketing or joining reform groups.

A hearing for McCrudden will take place on two charges of lying about making contact with felons after his release from prison.

McCrudden had been held without bail since his arrest on the recent case in November.

Neither McCrudden's attorney nor federal prosecutors could be reached immediately for comment.
