Mark Hasey's Execution Style

Kauffman County DA Mike McClelland and his wife Cynthia were found shot to death in their home on March 30, 2013. A week into the investigation, promising leads were simply not existent. Four weeks later, a tip came in about two lads talking about Mark Hasey's murder at a Texas bar. But there wasn't enough information in the tip to follow up on it as the tipster was anonymous. The hunt for the killer started to ramp up with vigor as things got worse.
