Federal court records indicate that on Oct. 31, 2007, Michael Algiere entered the Oakland Pharmacy wearing a ski mask while holding a knife.
The defendant demanded oxycodone from the pharmacy counter, fleeing moments later with a handful of different painkillers but DNA evidence found at the scene initially did not provide a match.
Then in February of last year, a routine comparison by the Maine State Police crime lab showed DNA evidence found at the scene was a match to Algiere.
The 32-year-old was indicted last August. He now faces up to 20 years in prison and a $250,000 fine. He will be sentenced at a later date.
