A man charged with killing the 2-year-old son of Minnesota Vikings running back Adrian Peterson in South Dakota last fall says the child choked on strawberry fruit snacks while he was in the bathroom.

The Argus Leader reports (http://argusne.ws/1nbAob7 ) Joseph Patterson, 28, is facing second-degree murder, manslaughter and aggravated assault charges in the death of two-year-old Tyrese Ruffin.

Patterson gave his version of events through his lawyer as he appeared in court Thursday for a motion hearing.
