A Buffalo man has been convicted of a fifth felony after a jury found him guilty of second-degree assault for slashing another man across the face in an East Side corner store and then stabbing him in the arm and chest as the victim tried to defend himself.

Jonathon Archibald, 41, was convicted last week after a weeklong trial in the May 7, 2013 knife attack in the store at Harmonia Street and Walden Avenue following an argument.

He faces a maximum prison term of 12 years to life at sentencing June 20 if State Supreme Court Justice M. William Boller determines that he is a persistent felony offender, according to Erie County District Attorney Frank A. Sedita III.

Archibald has three felony drug convictions as well as an attempted robbery conviction for slashing another man across the face with a razor blade and taking his cellphone in 2010 on Harmonia, Assistant District Attorney Justin T. Wallens said.
