Osborne, whose role in the affair remains unclear, is awaiting trial in Fort Worth on charges of being a felon in possession of ammunition. Authorities found a few bullets when they questioned him a year ago. His trial is set for April 24. His federal public defender, Robert Herrington, says Osborne believes he is being aggressively prosecuted on the ammunition case to pressure him to become a federal witness against Waters and Karr.
"They've expressed an interest in talking to him, but I've basically said, 'What's the point?'" Herrington says. "Mr. Osborne does not know who killed the O'Hairs. He did not kill the O'Hairs, and he does not know anything about their missing money. As a result, we don't know what we can say to the government to satisfy them."
