From The Daily Beast:
Oklahoma Politician Never Gave Up on Killer Son
|Commissioner Mark Costello and some of the rest of the Oklahoma attendees
at the Americans For Prosperity National Conference, this past weekend.
“Mark was trying to do the right thing to help his son, Christian, because of his mental health issues. Nobody in their right mind would do what [Christian] did yesterday,” a source close to the family told The Daily Beast. “Christian suffered some paranoid delusions regarding his parents, that they were plotting against him, that sort of thing,” the insider added.
