I knew about Peterson's dad (money laundering).
But I didn't know about this:
When he was thirteen years old his father was sentenced to ten years in prison for money laundering in connection with illegal drugs. Nelson Peterson served nearly eight years of his prison sentence and was released in October 2006. His brother was hit and killed by a drunk driver while riding his bicycle as a kid. His stepbrother, Chris Paris, was shot and killed in Houston, Texas, one day before Adrian's participation in the 2007 NFL Scouting Combine.
