A St. James man accused of having sex while driving and causing the death of 2 women has been sentenced to over 4 years in prison. The fatal crash occurred in August of 2011. 24-year-old Mark Anders Chalin was driving with 23-year-old Amber Menezes of Mankato on his lap on Blue Earth County Road 90 when he crossed the centerline and crashed head-on into 35-year-old Jonna Martin of Lakefield. Both women were killed in the crash, and Chalin was seriously injured. The 50-month prison sentence comes after he pleaded guilty to two counts of criminal vehicular homicide in an Alford Plea. There is the possibility of supervised release after about three years. In court on Monday, Blue Earth County Judge Bradley Walker implored everyone present to think about how someone’s life can change in an instant.
