A northwest Iowa man goes on trial for the murder of his son today. 38-year-old Donald Boss of Remsen has implicated his wife in the slaying of his ten-year-old adopted son, Timothy, nearly two years ago. The body was found buried in the basement of the family’s home. Lisa Boss is a material witness in the case and is under round-the-clock watch but has not been charged. Trial could last three to four weeks.
