Deadly DUI Lands Montco Man Prison Time

GLENSIDE, PA — A Glenside man who struck and killed a woman walking her dog in 2021 will spend several years in prison.

Michael Petrocik, 65, of Glenside, was sentenced to three to 6 years in prison for killing 61-year-old Mary T. Duffy on Dec. 29, 2021.

Duffy was struck and killed while walking her dog at about noon that day along the 3000 block of Philmont Avenue in the Huntingdon Valley section of Lower Moreland Township.

Petrocik was charged with felony counts of homicide by vehicle and homicide by vehicle while DUI, as well as three separate misdemeanor DUI counts and additional summary citations.

Duffy was walking her dog along the 3000 block of Philmont Avenue in Huntingdon Valley a little after 12 noon when an Audi driven by Petrocik failed to navigate a turn, left the roadway, crossed a berm and a grassy area and crashed into Duffy, knocking the woman into a pole, according to the Montgomery County District Attorney's Office.

Duffy's dog survived the accident.

After striking Duffy, Petrocik continued across an asphalt driveway and a yard before hitting a stone wall and launching airborne before coming to a rest, according to prosecutors.

Prosecutors said that lab testing revealed that Petrocik was under the influence of multiple substances at the time of the crash.

A police criminal complaint in the case states that Petrocik appeared impaired when questioned by Lower Moreland police at the scene, and that the defendant reportedly admitted to officers that he was on prescription medication and that he said he couldn't recall what happened at the time of the crash.

A forensic toxicology report subsequently showed that Petrocik had Valium in his system along with THC, which is the active ingredient in marijuana; Prozac; Wellbutrin; and other substances, according to the criminal complaint.

When Lower Moreland police arrived at the accident scene, they found Duffy lying on the sidewalk and saw the Audi stopped approximately 164 feet away from Duffy, according to the DA's Office.

Duffy was subsequently transported to Abington Hospital's Trauma Center, where she underwent emergency surgery but was later pronounced dead.
