ST. PAUL -- A Minneapolis man was sentenced to 11 years in prison Friday for selling heroin in the Bemidji area and two co-defendants will also serve time in a case officials described as the “largest heroin seizure in northern Minnesota.”

According to a news release from the U.S. Attorney’s Office, Raymond Walker, 30, Minneapolis, was convicted of one count of conspiracy to distribute heroin and was the “leader, manager and organizer of the conspiracy, (and) supplied large quantities of heroin throughout Bemidji and the Red Lake Indian Reservation.”

Co-defendant Luis Martinez, 30, address unknown, received a sentence of one year and five months in prison and Miranda Morrison, 26, of Hines, Minn., was sentenced to three years and four months.

According to the defendants’ guilty pleas and court documents, between July 29, 2015, and Aug. 20, 2015, Walker, Morrison and Martinez conspired to distribute more than 256 grams of heroin throughout the Bemidji area.

Morrison was arrested on Aug. 20, 2015, after an $8,000 “heroin transaction.” Law enforcement seized $12,000 from her vehicle and discovered Walker had given her the heroin.

Law enforcement searched Morrison’s vehicle six days later and found more than four pounds of heroin and two digital scales, according to the release.

The trio was in indicted in federal court in February 2016. All three pleaded guilty to one count of conspiracy to distribute heroin.

This case was investigated by the Paul Bunyan Drug Task Force, FBI Headwaters Safe Trails Task Force, Bureau of Indian Affairs, Red Lake Department of Public Safety and Minnesota Bureau of Criminal Apprehension.
