Lavender’s arrest follows an investigation by Bucks County officials that began with the overdose death of 25-year-old Nikki Lee Silva in July.

Investigators determined that Lavender was the person who supplied the drugs to Silva after an interview in August.

During that interview, Lavender admitted that he took Silva to Kensington where he bought six bags of fentanyl from a street dealer, according to the release.

“They’re all fentanyl,” Lavender said during the interview with Bucks County officials. “There is no heroin no more.”

After buying the drugs and giving them to Silva, an autopsy determined she died of accidental acute fentanyl intoxication and a toxicology report found she had fentanyl and norfentanyl in her system, according to a release.

When police responded to a report of a female in cardiac arrest in July, they also say they found three used and two unused baggies containing heroin or fentanyl on the scene.
