OAKLAND A man who allegedly struck it rich through fentanyl sales in the Bay Area has been sentenced to seven years in federal prison, court records show. Milton Varela-Arteaga, 29, was sentenced last month by U.S. District Judge Charles Breyer, after pleading guilty to possession with the intent to distribute fentanyl. He must serve a four-year supervised release term afterwards, but because he's already been deported to Honduras once, a similar fate likely awaits him after completion of his prison term, according to court records.
