Erie County District Attorney Frank A. Sedita III said Thursday that he plans to recommend the maximum prison term for Alfred Mack, the 58-year-old Buffalo ex-convict who was found guilty last week of burglarizing the house of an estranged girlfriend who had obtained a court order of protection against him a week before the break-in.

Sedita said he will ask State Supreme Court Justice Deborah A. Haendiges to impose the maximum-allowable 15-year prison term on Mack when the Dewey Avenue man is sentenced at 2 p.m. May 16.

Mack took the stand during his weeklong jury trial and claimed he thought he still had legal permission to enter the home of his estranged girlfriend, who lived down the street from him on Dewey Avenue.

The jury found him guilty as charged of second-degree burglary and first-degree criminal contempt for violating the judge’s Feb. 27 order of protection.

During the trial, the victim testified that Mack broke into her house through a back window and was arrested after neighbors heard her screams for help. She said that as he began punching her some neighbor men showed up and he tried to flee but was knocked to the ground outside her home until police arrived.

Sedita said Mack has an extensive felony criminal history, and he praised the two prosecutors in the case, Rachel Newton, head of his Domestic Violence Bureau, and Alicia Lilley. He said both prosecutors “demonstrated through this conviction that our office will continue to aggressively prosecute those who commit criminal acts of domestic violence.”
