LITTLE FALLS -- A Minneapolis man has been convicted of third degree murder after he sold heroin that led to the overdose of a Little Falls woman.

Morrison County charged 30-year-old Keon Mangun with the crime after 19-year-old Miranda Gosiak overdosed February 28th, 2012.

Assistant County Attorney Todd Kosovich says "This is a major victory on heroin." He says "In this case we went after the heroin dealer himself."

The jury deliberated for only three hours in the case.

Mangun is scheduled to be sentenced November 27th. He is expected to get just over 11-years in prison.
