CBS News' "48 Hours" program is examining the Murdaugh murder case through interviews and evidence that played key roles in the conviction of Alex Murdaugh.

The program features correspondent Nikki Battiste speaking with two longtime friends of Maggie Murdaugh, who was killed alongside her son Paul in June 2021. The friends are working to preserve Maggie Murdaugh's memory and share insights into her life before the tragic events.

A significant focus of the CBS coverage involves Paul Murdaugh's cell phone video, which became crucial evidence in the prosecution's case against his father Alex Murdaugh. Prosecutors have described the video as Paul "leaving something behind that lets you know what happened to him," according to statements made to the "48 Hours" program.

The cell phone evidence proved instrumental in Alex Murdaugh's conviction for the murders of his wife Maggie and son Paul. The video helped establish timeline and location details that contradicted Alex Murdaugh's initial statements to investigators.

Alex Murdaugh was ultimately convicted in March 2023 for the murders and sentenced to life in prison. The case garnered national attention due to the family's prominent legal and political connections in South Carolina's Lowcountry region.
