All charges were dismissed Monday against Alan J. Roscetti, a Niagara Falls attorney who had been charged last month in a domestic violence case.
Roscetti, 38, an assistant Niagara County public defender, ran unsuccessfully for Falls city judge this year.
A nonjury trial was called off in North Tonawanda City Court. Roscetti's attorney, Camille Sarkees Brown, said the prosecutor had "no credible witnesses or any evidence."
"The alleged victim refused to cooperate," said Joanna Pasceri, spokeswoman for the Erie County District Attorney's Office.
The Erie County DA's office assigned a special prosecutor after Niagara County District Attorney Caroline A. Wojtaszek recused herself and her staff. Pasceri noted the alleged victim hired a fellow public defender of Roscetti's as her counsel.
