RAPID CITY, S.D. (AP) — An 18-year-old Rapid City man has been sentenced to 40 years in state prison for a fatal shooting in 2018. A judge Monday sentenced Ronald Black Cloud in the death of 43-year-old Nathan Graham. Black Cloud was found guilty last October of second-degree murder. Black Cloud was sentenced under a set of rules that prohibit minors from being sent to prison for life without a chance of parole. He was 14 when the crime was committed. Black Cloud will receive about 3 1/2 years of credit for time he has spent in the county jail.
