MONTGOMERY COUNTY, Pa. - Renee DiPietro, charged with third degree murder in the death of Michael Sides has been found guilty.
A jury returned the verdict late Thursday afternoon.
Prosecutors say the 70-year-old woman stabbed the 31-year-old victim with a 16-inch blade sheathed in her cane outside an Ardmore bar last June and then took off.
Montgomery County prosecutors said she inserted herself into a fight between Sides and her son.
The jury saw the sequence of events and the incident on surveillance video. The jury took just over five hours to return the guilty verdict.
DiPietro, speaking outside the courtroom, maintained she acted in self-defense.
"It was wrong," DiPietro said, as officers led her away. "If it was their child…if it was their child, what would they do?"
