A rural Montgomery teen facing life in prison for allegedly killing his father was in court Tuesday for an omnibus hearing. 18-year-old Jonas David Nelson is accused of shooting 47-year-old Richard Nelson in the head in early January while he was sleeping. The younger Nelson allegedly told police that he had shot his father because of “the way he was being treated.” A grand jury was convened in March, and Nelson was charged with 1st-degree murder. In court Tuesday, prosecutors referenced a letter Nelson reportedly wrote to a judge in January that implied that he planned to use his father’s life insurance payment to hire private attorneys. Minnesota law prohibits someone accused of first- or second- degree murder from using life insurance money from their alleged victim. Nelson remains in custody, and his next appearance in court is September 30th.
