 A white bear lake man is now charged with second-degree murder in the death of his three-month-old son. The Hennepin County Medical Examiner's Office says Jackson Forrester died in the hospital March 22 of complications due to blunt force head trauma. Prosecutors say 39-year-old Mark Forrester is accused of shaking then-eight-week-old Jackson on January 31 before the boy's mother brought him to the hospital. The criminal complains as Mark Forrester admitted he may have done something to his son but didn't remember because he'd been drinking.
