The coldest cases from Middletown, USA

With dozens of unsolved murders spanning decades, Muncie and surrounding Delaware County might have more killings without justice than any American community like it. In 1962, Maggie Mae Fleming was shot to death as she sat in her living room. Paula Garrett was bludgeoned in her home in 1979, and her son, who survived the attack, wants justice. Garth Rector, killed in 2008, could have been murdered by any number of people he knew--or dated.

Journalists and award-winning true crime authors Douglas Walker and Keith Roysdon shine a spotlight on the victims, and on their loved ones and the investigators still hoping for resolution to long-cold murders.
