A Warren man has pleaded guilty to changes including involuntary manslaughter in connection with a December fentanyl death.

Christian L. Papalia, 19, Warren, entered the plea to charges of involuntary manslaughter and possession with intent to deliver before President Judge Maureen Skerda on Thursday morning.

First Assistant District Attorney Cody Brown said that Papalia is “not a typical drug dealer.”

He said that Papalia traded two pills that he believed to be percocet to the victim for a ride to Erie.

The criminal information that Skerda presented said that the controlled substance appeared to be percocet but was “unknowingly fentanyl.”

Pennsylvania’s involuntary manslaughter statute requires “reckless or grossly negligent” conduct and Skerda said that action in this case “result(ed) in the victim’s death.”

Papalia had been charged with drug delivery resulting in death.

That offense — a first-degree felony — was withdrawn by the District Attorney’s office when the criminal information was filed on Tuesday.

At that time, charges of involuntary manslaughter, a misdemeanor, and possession of drug paraphernalia were added.

In exchange for the plea on Thursday, the possession of drug paraphernalia charge was not prosecuted.

Brown said the prosecution would not oppose a county sentence and noted that Papalia has no prior criminal record.

He called for a sentence in the range of six to nine months with drug treatment to follow.

Skerda asked Papalia why he was there Thursday.

“I made a mistake,” Papalia said.

The maximum penalties on these offenses are both five years incarceration.
