Man Accused In Vikings Son's Death Pleads Not Guilty
(Sioux Falls, SD) -- The man accused in the death of Vikings Star Adrian Peterson's son has pleaded not guilty to charges he allegedly attacked the South Dakota mother. Joseph Patterson was arrested in June after police say he attacked the mother of two-year-old Tyrese Ruffin in the Sioux Falls area and held her against her will. The 28-year-old was living with the same woman last October when he was accused of beating Ruffin to death. Patterson is set to go on trial in each case in the coming months.
