The Texas death row inmate, who is 52 years old, is accused of raping and murdering a woman named Stacey Stites in 1996.
Police said it was just days before the 19-year-old's wedding when her body was found along a highway in Bastrop County. Authorities arrested Reed after his DNA matched the DNA found inside her body.
However, Reed maintains his innocence, saying he and Stites were having a consensual affair. Reed's supporters say Stites' fiance is the one to blame.
The case gained national attention in 2019.
Reed was granted a stay of execution, following a public outcry from celebrities and advocates such as Beyoncé and Kim Kardashian West.
Stites' family believes Reed is guilty.
In the "20/20" episode, you will hear an exclusive interview with Carol Stites, who is Stacey Stites' mother, as well her sisters Crystal Dobbs and Debra Oliver.
Carol Stites opens up about the memories she has of her daughter and the heartbreak of losing her.
The program will also feature Correspondent Deborah Roberts’ death row interview with Reed, conducted just weeks before his scheduled execution.
