An 18-year-old mother is charged with second-degree murder in the death of her young son in southwestern Minnesota last weekend. Sandra Highbear of North Redwood Falls has been charged in Redwood County. She's accused in the death of her 22-month-old son Conroy. According to the complaint, police were called Saturday night to a Redwood Falls home where Highbear was living on a report of a child not breathing. Officers found Conroy lying on a couch and his mother in the kitchen crying. Officers tried to revive the boy, but he was pronounced dead at a hospital. An autopsy found the boy had bruises and died from peritonitis due to a ruptured stomach. Unconditional bail is set at $2 million. Highbear remains in jail.
