A Tredyffrin man has been arrested for allegedly dealing heroin that ultimately resulted in an overdose death.

The Chester County District Attorney's Office said today that Dillon Quinn is being charged in connection with the August death of 19-year-old Colin Finn.

"This case is a grim reminder to all heroin dealers and users," District Attorney Tom Hogan said in a statement. "Heroin will lead you straight to jail or your grave."

Officers were called to a home in Berwyn on Aug. 8 and found Finn dead in his bed, prosecutors said. Heroin packets were found at the scene, and an autopsy and toxicology tests showed he died from a heroin overdose.

Prosecutors allege that Quinn, 19, bought the heroin found in Finn's home from another person near the Overbrook train station in Philadelphia, then sold some of that heroin to Finn.

The pair then returned to Chester County, where Finn took the heroin, overdosed and died.

"Every drug dealer knows that the poison they are distributing could kill somebody," Hogan said.

Court documents say the two exchanged text messages in the days prior to Finn's death, making arrangements for the heroin deal.

In an interview with detectives in late August, Quinn admitted to paying for the heroin with money he obtained from Finn, and to providing Finn with the drugs, according to court documents.

He expressed remorse for the death, the documents say, and told the detectives, "I killed my best friend."

Quinn faces charges that include drug delivery resulting in death and other drug offenses. He is being held at the Chester County Prison on $200,000 bail.
