Heroin dealer convicted despite ‘Dookhan defense’

The so-called “Dookhan defense” did not work for one Boston heroin dealer who was convicted by a Suffolk Superior Court jury despite his claim that indicted chemist Annie Dookhan may have tampered with key evidence in the case, prosecutors said.

The defendant, 58-year-old Julio Medina, is one of thousands of convicted and alleged drug offenders who are seeking acquittal or to have their cases dismissed or overturned because of allegations that Dookhan mishandled drug evidence at a state lab where she worked for nine years.
