 A 26-year-old Redby man has been sentenced to 30 years in prison for the violent beating death of his 23-month-old son. Gary Wayne Jackson Jr. pleaded guilty to second-degree murder on June 20. He was sentenced today in U.S. District Court in Bemidji. According to his guilty plea and documents filed in court earlier this year, Jackson in a fit of rage repeatedly punched his 23-month-old son, resulting in the child's death. Following the assault, Jackson failed to seek appropriate medical care for his son. The final autopsy report revealed the cause of death as blunt force trauma to the head and torso. His case is the result of an investigation conducted by the FBI Headwater's Safe Trails Task Force and the Red Lake Police Department.
