Commonwealth of Pennsylvania v Larry Shroyer

Blue drug packets connect dealer to overdose death

Crime On November 13, 2015, George Duke, Jr. died in his bedroom after overdosing on a mixture of heroin and butyryl fentanyl.
Evidence Three blue drug packets were collected as evidence.
DNA The Pennsylvania State Police crime laboratory processed the drug packets, and developed DNA mixture data.
Match The lab couldn’t fully interpret the mixtures. Their methods needed more DNA to analyze the minor component. So Bradford Police Chief Chris Lucco contacted Cybergenetics for a TrueAllele computer analysis.
TrueAllele The computer connected the three blue packets to drug dealer Larry Shroyer with a match statistic of a thousand. Only 1 in ten thousand people would match as strongly by chance.
Cybergenetics    On October 29, 2019, DNA analyst Jennifer Bracamontes testified before a McKean County jury about the TrueAllele results.
Outcome On November 1, Mr. Shroyer was found guilty of all drug charges, recklessly endangering another person, and fleeing from the police. President Judge John Pavlock sentenced him to serve 53 to 106 months in prison.
