"48 HOURS" SATURDAY NIGHT DOUBLE FEATURE

48 HOURS: "Missing Marsha" 9:00 PM

48 HOURS: "Knock Knock" 10:00 PM

48 HOURS tackles two cases filled with twists, contradictions and more in a Saturday night double feature to be broadcast Saturday, June 29 (9:00 PM, 10:00 PM, ET/PT) on the CBS Television Network.

At 9:00 PM, Peter Van Sant and 48 HOURS investigated the disappearance of Marsha Brantley of Cleveland, Tenn., and the murder case against her husband, Donnie Brantley in an encore of "Missing Marsha."

The Brantley case was unusual from the start because for months after Marsha disappeared in 2009, nobody reported her missing - not her friends, family or even her husband. No one took much notice until her hairdresser, Kelly DeLude, worried about a missed appointment, started asking. DeLude eventually called police and investigators later picked up the case. Donnie Brantley claimed he hadn't reported Marsha missing because she had left him. Then, police say he lied repeatedly about where she had gone and what she'd taken with her. Still, there was no physical evidence of a crime - no blood, no fingerprints, no crime scene at all. The investigators' biggest hurdle in solving the disappearance of Marsha Brantley, may have been Marsha herself. There was no dead body to prove a murder ever had been committed.

Donnie Brantley was arrested in 2013, but then prosecutors dropped the charges after deciding they didn't have enough to get a conviction. Two years after his 2014 election, District Attorney General Stephen Crump charged Brantley again with essentially the same evidence. Then, February 2018, just before trial, Crump dropped the charges against Brantley, shocking everyone.

What happened to Marsha Brantley?

At 10:00 PM Richard Schlesinger and 48 HOURS report on the investigation into the deaths of two beloved grandmothers - Betty Jones and her friend Kathryn Crigler - in Starkville, Miss., on Labor Day in 1990 in an encore of "Knock Knock." The case, which was unsolved for three decades, prompted Betty Jones' step-grandson, Jason B. Jones, to spotlight the case in a podcast. Jones, who was 10 when his grandmother was murdered, launched his podcast in September 2017 as a way to work through his own questions about the incident and, perhaps, have someone uncover new information. But what began for 48 HOURS as a story about a cold case turned into something much different, thanks to Starkville detective Bill Lott's determination and cutting-edge DNA technology that didn't exist when the women were killed.
