 Three individuals from Minnesota have been sentenced to prison in connection with a large-scale heroin distribution ring in the Bemidji area and the Red Lake Indian Reservation. Authorities say 30-year-old Raymond K. Walker of Minneapolis was the leader of the operation and supplied large quantities of heroin throughout the Bemidji area and the Red Lake Indian Reservation. Acting United States Attorney Gregory G. Booker says Walker conspired with 30-year-old Louis Manuel Martinez whose hometown is unknown and 26-year-old Miranda Jo Morrison of Hines to distribute heroin and collect thousands of dollars in illegal drug money on behalf of the conspiracy. According to court documents between July 29th of 2015 and August 20th of 2015, the three individuals conspired to distribute more than 256 grams of heroin throughout the Bemidji area. Walker was sentenced to 132 months in prison with five years of supervised release. Martinez was sentenced to 17 months in prison with three months of supervised release and Morrison was sentenced to 40 months of prison with five years of supervised release. All were found guilty of one count of conspiracy to distribute heroin.
