It's day four of the Donald Southworth murder trial with a focus on his actions the day of his wife's murder. Umi Southworth was found dead in Lexington on June 9, 2010. Southworth's supervisor at UPS testified that Southworth was never late for work but that day, he was. The supervisor says he missed his shift completely then showed up and insisted on working, which the supervisor says he found to be odd.
