LOCKPORT - A Town of Niagara man, accused of using a blunt metal object to assault a pro boxer in a reported fight over a woman, gave a DNA sample today after Niagara County prosecutors agreed not to use it in any other cases.

Michael P. Vicki, 30, of Portland Street, is scheduled for trial Dec. 3 on charges of first-degree assault and third-degree criminal possession of a weapon in connection with the May 12 beating of junior welterweight contender Nick Casal, 22, of Niagara Falls, which occurred at Vicki's house.

After a previous court appearance, defense attorney Mark D. Grossman said a DNA test might bolster Vicki's claim of self-defense, because it might show some of the blood spatter at the scene came from Vicki, not Casal.

Thursday, attorney James J. Faso Jr., standing in for Grossman, said Vicki would give the sample if prosecutors agreed to destroy it after testing and not enter it in the state DNA database. Assistant District Attorney Lisa M. Baehre agreed to those terms.
