48 Hours – August 7 2021 – 8/7/2021 – Saturday – CBS

9:00 PM, ET/PT – 48 HOURS: “Murder at the Mall” – Correspondent Jamie Yuccas and 48 HOURS report on the death of 18-year-old Michelle Martinko who went out to the local mall in Cedar Rapids, Iowa, on Dec. 19, 1979 and was later found dead in her car, in an encore of “Murder at the Mall: The Michelle Martinko Case” to be broadcast Saturday, Aug. 7 (9:00 PM, ET/PT) on the CBS Television Network. Martinko was stabbed and cut 29 times. Investigators looked at those closest to her as possible suspects, and questioned many of her male friends. The case baffled local police officers for decades, and kept them going through several generations, until they got a break from evidence Martinko left behind. The case came alive in 2005 when blood scrapings from the gearshift of Martinko’s car were sent out for testing. That lab report turned up male DNA – DNA that did not match anyone previously interviewed in the case, or anyone in the nationwide database of criminal offenders. It would take another decade – and a new detective. He turned to Parabon NanoLabs, which uses genetic genealogy to track DNA from one family member to another. Parabon found a distant relative of the killer. Did they have the killer? 48 HOURS takes viewers inside the unrelenting efforts by police to solve the case. Watch a preview.

10:00 PM, ET/PT – 48 HOURS: “The Case Against Nicole Addimando” ­– Correspondent Jericka Duncan and 48 HOURS have the latest on the investigation into the death of gymnastics coach Chris Grover, and the murder case against his partner Nicole Addimando in an updated encore of “The Case Against Nicole Addimando,” to be broadcast Saturday, Aug. 7 (10:00 PM, ET/PT) on the CBS Television Network. The death of Grover and the legal proceedings against Addimando divided the community in Poughkeepsie, N.Y. The case hinged on the question of whether Addimando murdered Grover or she was, as she argues, acting in self-defense against an abusive partner. The story begins on Sept. 28, 2017, when a police officer spotted a car stopped at a green light. When he sounded his air horn to get the car to move, an agitated Addimando got out and told him something had gone terribly wrong at home. She told police that her partner Grover had abused her for years. She said things reached a boiling point when Grover came home from work that day, after Child Protective Services visited to investigate an anonymous report earlier that morning. At one point that night, she said, they lay down on the couch together and Grover pulled a gun from the cushions. When Addimando asked to leave, by her account, he said he would kill her. Addimando said she got the gun away from Grover and shot him in self-defense. Addimando was convicted of second-degree murder in 2019. An appeals court heard her case in April 2021. 48 HOURS has the latest on the appeal and a decision that continues to split the community. Watch a preview.
