A Metairie man has been sentenced to 12 years in prison for drug convictions stemming from a 21-year-old man's fatal heroin overdose in 2008.
Federal prosecutors say 32-year-old Matthew Olvany was the source of the heroin that Zachary James Mosier ingested on the day he died.
Olvany, who was sentenced Thursday by U.S. District Judge Mary Ann Vial Lemmon, pleaded guilty in January 2010 to drug charges.
