A Buffalo man pleaded guilty Friday to felony first-degree attempted assault for stabbing an acquaintance in the throat while waiting in line for food handouts from a truck aiding the homeless at 7 p.m. Sept. 28.

Haywood Barleston, 68, of Ellicott Street, pleaded guilty before State Supreme Court Justice Russell P. Buscaglia. Barleston stabbed Melvin Moore, 58, of Moeller Street with a knife while both waited in line at Ellicott and Clinton streets.

Erie County District Attorney Frank A. Sedita III said Barleston faces a mandatory prison term of from 3½ to 15 years when he is sentenced Dec. 20.
