A man jailed for failing to pay child support was arraigned Tuesday in Riverhead, N.Y., on charges that he conspired to buy a gun to kill the Suffolk County judge he claimed “gave his house away” to his ex-wife.

District Attorney Thomas J. Spota said at a news conference that Brian Orkiszewski, 49, “felt entitled to more” from the proceeds of the sale ordered by the judge identified by judicial sources as Supreme Court Justice William J. Kent III.
