Authorities in Sioux Falls, S.D., have issued an arrest warrant for the suspect in the death of the 2-year-old son of Minnesota Vikings running back Adrian Peterson.
The Minnehaha County Sheriff's Office says Joseph Patterson violated terms of his bail by contacting the boy's mother.
Patterson was released on $2 million bail in September. He's charged with second-degree murder, manslaughter and aggravated assault in the 2013 death of Tyrese Ruffin. Patterson also has pleaded not guilty to aggravated assault and kidnapping charges in an alleged attack on the boy's mother last June.
Patterson was living with the child's mother when he called 911 to report that the boy had stopped breathing. Doctors determined the boy's injuries couldn't have been accidental. Prosecutors allege Patterson beat Tyrese. Patterson maintains the child choked on a snack.
