GRAND FORKS, N.D. — The ex-roommate of a North Dakota man accused of making synthetic drugs that killed two people has been sentenced to prison for his role in the crime.

William Fox, 24, of Grand Forks, has been sentenced to four years in prison for distributing the synthetic hallucinogens allegedly made by his roommate, Andrew Spofford. Fox faced up to 30 years in prison.

Several other people facing charges in the case are set to be sentenced next week.

Police said 18-year-old Christian Bjerk, of Grand Forks, and 17-year-old Elijah Stai, of Park Rapids, died of apparent drug overdoses from the hallucinogens. Authorities said at least five others were hospitalized with overdoses.
