A Bucks County woman is facing criminal charges after she supplied the drugs that led to the death of her roommate last year, according to the District Attorney’s Office.

Mary Wells, 34, was found unresponsive at a home on the 4300 block of Dover Drive in the Pennwood Crossing trailer park that she shared with Christina Gallo, 38, on Jan. 2, 2025, officials said.

Wells was taken to a nearby hospital where she was pronounced dead.

During an autopsy and toxicology report, it was discovered that Wells died from a deadly combination of drugs that included fentanyl, xylazine (Tranq), methamphetamine, methadone and para-fluorofentanyl, officials announced.

While inside the trailer home, investigators said that they found straws and blue wax bags. Those items were tested in a lab and were found to contain a strong mix of fentanyl, xylazine, and para-fluorofentanyl.

Through the investigation, it was discovered that Wells used fentanyl every day and had become too sick to leave her home in the days that led up to her death, officials said.

Despite Gallo telling authorities that other people had supplied the drugs to Wells, investigators said they learned Gallo would regularly drive to the Kensington section of Philadelphia to buy fentanyl.

Text message exchanges between the two women in Dec. 22, 2024, showed the women express excitement over being able to buy a specific kind of fentanyl, officials reported.

Investigators said that Gallo brought the final, and fatal, delivery of fentanyl to Wells on Jan. 1, 2025.

Gallo is also accused of using Wells’ debit cards to make purchases for herself and withdrew money which ultimately emptied her roommate’s bank accounts, the family told investigators.

“The details of this case are as heartbreaking as they are infuriating,” Bucks County District Attorney Joe Khan said. “Not only did the defendant deliver the very poison that ended the victim’s life, but she then chose to further victimize the family by systematically draining the victim’s financial accounts in the days following her death.” 

Gallo was charged with drug delivery resulting in death, possession with intent to deliver a controlled substance, involuntary manslaughter, identity theft, access device fraud, theft by unlawful taking as well as recklessly endangering another person

She was arraigned on March 10, 2026, and is being held at the Bucks County Correctional Facility under $250,000 bail.

A second person, identified as 44-year-old John “Twitch” Lindsay, is also accused of delivering methamphetamine to Wells during the same period, officials said.

Lindsay was charged with possession with intent to deliver a controlled substance and was sent to Bucks County Correctional Facility on $50,000 bail.
