MEDIA — District Attorney Jack Stollsteimer announced the arrest today of Mackenzie Sarah Allen, 25, of Glenolden, on charges of drug delivery resulting in death, involuntary manslaughter, and delivery of a controlled substance, and other related charges. The charges result from the May 21, 2021 overdose death of a 30 year-old male victim at his residence in Glenolden.

“When we can prove that an individual distributed the drugs that resulted in an overdose death, that individual will be charged with murder. However, such prosecutions are not our preferred tool for dealing with the scourge of opioids in our community. We must continue to educate residents about the dangers of these drugs, and we must continue to make sure that Narcan is available to anyone who needs it, free of charge and free of stigma. Narcan is cheap and easy to administer – and while it might not have been possible to save this victim – it has saved countless lives.” said Stollsteimer.

At approximately 7:15 in the morning on May 22, 2021, Darby Township Police responded to a report of cardiac arrest at 233 Spruce Street, Glenolden, in the township of Darby. The thirty- year-old male victim was found unresponsive on the bed and CPR was attempted. Medical personnel also responded; despite those efforts, the victim was pronounced dead at the scene. A female witness who was also on location had attempted CPR on the victim prior to the arrival of the police and medical personnel. An autopsy was conducted, and the medical examiner determined that the cause of death was complications from fentanyl intoxication.

Responding officers asked the witness whether the victim had taken any controlled substances recently, to which the witness responded in the affirmative. She stated that at approximately 2:00 pm on May 21, 2021, the witness and the victim had met up with an individual by the name of “McKenzie” on Stratford Road in Glenolden and that they had purchased seven Xanax pills for $35.00. Both the victim and the witness took some of the Xanax without any adverse reaction.

Officers conducted a brief search of the premises and recovered a white wax paper fold that was on the floor near to the victim’s body. The paper was partially ripped, and bore an imprinted stamp of a Lamborghini logo. The officers also recovered the victim’s cell phone. A search of the cell phone revealed that the victim had contacted “McKenzie” with a text message asking “is there any way you can spare 2 bags.” Further investigation revealed that the cell phone number for “McKenzie” in the victim’s phone matched the information in the PennDot system for a Mackenzie Allen who resided on Stratford Road in Glenolden.

On June 4, 2021, officers executed a search warrant at 309 Stratford Road, Glenolden. Officers discovered numerous empty wax paper folds with various stamps on them, including eight with the Lamborghini logo identical to the paper found on the premises of the victim. On September 13, 2021, the Pennsylvania State Police Bureau of Forensic Services confirmed that the wax paper recovered from the victim’s premises contained fentanyl. On September 15, 2021, the State Police Bureau reported that the wax paper marked “Lamborghini” and recovered from the defendant’s premises contained fentanyl.

“I want to thank the Darby Township Police Department, particularly Narcotics Task Force member Criminal Investigator Sean Gallagher, as well as Criminal Investigation Division Detective Anthony Ruggieri work their work on this case. The determination of everyone involved to pursue justice on behalf of the victim and his family is to be commended,” said DA Stollsteimer.

A drug delivery resulting in death charge is issued to a person who intentionally administers, dispenses, delivers, gives, prescribes, sells or distributes any controlled substance or counterfeit controlled substance and another person die as a result of using the substance. The charge carries a maximum possible sentence of 20 to 40 years in prison.

The defendant is being held at the George W Hill Correctional Facility. Bail was set at $500,000, cash. Her preliminary hearing is scheduled before the Honorable Steven A. Sandone on February 1, 2022.
