FARGO — A U.S. District Court Judge has sentenced a Williston, North Dakota, man, LaSamuel Richardson III, to 10 years in prison followed by three years of supervised probation for his conviction on a charge of being a felon in possession of firearms and ammunition.

According to information released by Acting U.S. Attorney Nicholas Chase:

A female resident of Fargo reported that a man was masturbating in a vehicle outside of her residence on Jan. 4, 2019. Richardson became a suspect after the caller's neighbor spotted the same vehicle in front of the same residence three days later.

Police ran the vehicle’s license plate through the North Dakota Sex Offender Registry and learned Richardson had identified the vehicle as his primary vehicle when he last registered with the Williston Police Department.

After identifying Richardson, 32, as a suspect, Fargo police learned he was subject to GPS monitoring.

GPS records indicated Richardson had been outside the address of the female complainant on Jan. 4 and Jan. 7, 2019.

Police later found Richardson in his vehicle in a parking lot near Island Park. But before uniformed patrol officers could arrive to arrest Richardson, he got out of his vehicle and entered a vehicle driven by a female acquaintance.

Officers later initiated a traffic stop of the woman’s vehicle, after which they recovered 12 rounds of 9mm ammunition in Richardson’s coat pocket. The woman later provided federal authorities with a loaded 9mm pistol that Richardson hid in her vehicle during the traffic stop.

A search of Richardson’s vehicle parked near Island Park yielded an AR-15 rifle and 35 rounds of .223 ammunition that could be fired from the rifle found in Richardson’s vehicle.

A jury in February found Richardson guilty of being a felon in possession of firearms and ammunition.
