An arrest warrant is in place for Adrian Peterson and most expect him to turn himself in soon. According to sources the investigation has been quietly going on behind the scenes for a couple months but everything is coming to a head today. A text message conversation between Adrian and his son’s mother has been made public where AP acknowledges what he did to his son after he returned home to his mom.
