‘Looked Like a Cold-blooded Killer’: Judge Slams 70-Year-Old Woman Who Stabbed Man with Sword Hidden In Cane While Defending Son; Sentences Her to Up to 40 Years

A 70-year-old woman who was found guilty of killing a man by stabbing him with a blade hidden inside her cane will spend between 20 and 40 years behind bars for the crime.

Renee DiPietro was sentenced Monday after being found guilty of third-degree murder in the death of 31-year-old Michael Sides in Ardmore, Pennsylvania.

Investigators learned DiPietro stabbed Sides on June 10, 2023, following an incident in which her son “sucker-punched” one of Sides’ friends at a bar for flirting with his girlfriend.

DiPietro’s son was kicked out of the bar, so he called his mother and father to pick him up. Prosecutors said Sides, who was bartending at a nearby pub, heard about the fight and went outside to find the guy who punched his friend.

Sides confronted DiPietro’s son just as he was getting into his parents’ car and started fighting him.

DiPietro intervened in the fight, pulled a 16-inch blade from her walking cane that doubled as a sheath and stabbed Sides.

Prosecutors said surveillance video showed DiPietro stabbing Sides once after he confronted her son, and then another time after he fell to the ground.

A jury convicted her of murder in January and rejected her claim that she was acting in defense of herself and others.

“He came at me. I never came at him. I’m sitting in jail. What did I do?” DiPietro said from her wheelchair at the defense table during her trial. “You don’t think I hurt? I see his (Sides) face every day. I am sorry for what happened to that young man.”

She maintained her self-defense claim even after a judge announced her decades-long sentence this week.

“I apologize for what happened to him, but I did not kill him,” DiPietro said as she was wheeled out of the courtroom. “I did not take his life. He came upon me.”

The judge rejected the notion that DiPietro was acting in self-defense. Prosecutors played surveillance video in court that showed no one in DiPietro’s party called police or tried to help Sides after he was stabbed.

“Nothing justified the murder of Michael Sides. The video does not lie. You looked like a cold-blooded killer in that video,” Judge Wendy G. Rothstein told DiPietro while referencing the surveillance footage. “You, not Michael Sides, escalated the situation. You stabbed Michael and stood over him and taunted him.”

Prosecutors weren’t gunning for the maximum sentence in this case. They wanted DiPietro to serve a standard prison term of seven to 20 years.

During DiPietro’s sentencing hearing, her attorney tried to get her sentence reduced, citing her age, failing health, and remorse, but the judge turned him down.

“Murder is murder, no matter the age of the defendant,” Rothstein said, telling DiPietro directly that she was only “remorseful” for her situation, not for what she did.

DiPietro will be incarcerated at a state institution with a medical department that can sufficiently address her medical needs as she ages.

The 70-year-old has vowed to appeal her conviction.

Still independent.

We hope this story was worth your time. For over 14 years, Atlanta Black Star has stayed Black-owned and independently run. We didn't get here by waiting on ad budgets that were never built to prioritize us. Our readers did that.

Corporate support for Black media has always been thin. Outlets like ours get roughly 1% of the $170 billion spent on U.S. advertising each year, and that margin is shrinking further as advertisers walk back the DEI-linked commitments they made in 2020. That's the backdrop. It's not why we're asking.

The wider picture isn't any steadier. Newspaper ad revenue has fallen more than 80% since 2005, and local newsrooms are closing at a rate of roughly two a week nationwide. When outlets go under, it's rarely the ones built to center a Black perspective from the ground up that get to stick around.

We know a request for support isn't why you came here. But without readers choosing to fund this work directly, the depth of reporting we can do at home and abroad shrinks along with everyone else's. If you're not in a position to give, that doesn't change how much we value you as a reader.

If you are able to, a recurring contribution does more for us than a single one-time gift, because it lets us plan the next investigation instead of just the next invoice. It takes about 30 seconds, no long form, no account. Thank you for continuing to support independent journalism and freedom of the press.
