The South St. Paul woman who's 10-year old son was found dead in her home earlier this week has now been arrested. South St. Paul Police say they arrested Patricia Becht for the murder of her son Michael Becht, Jr., and for the attempted murder of her 11-year old daughter, who remains hospitalized. Police still are not saying how the boy died, or how the girl was injured. From early on in the investigation, police say they suspected Patricia Becht, who was also found to be injured when the boy's body was discovered Monday night. Charges have yet to be filed, but Becht is in custody at the Dakota County Jail.
