48 HOURS: "The DNA of a Killer" - More than two decades after an Idaho teenager was killed, New Orleans filmmaker Michael Usry, the producer of a short film about a brutal death, found himself the suspect in the teen's murder because of a DNA test being used by police today to solve cold cases. Anne-Marie Green and 48 HOURS investigate the 1996 death of Angie Dodge and technology that that led to Usry - and that helped police recently crack the infamous Golden State Killer serial murder case - in an encore of "The DNA of a Killer" to be broadcast Saturday, June 16 (9:00 PM, ET/PT) on the CBS Television Network.

Dodge was murdered in 1996. The killer left DNA on her body, which police believed would lead to the person who murdered the teen. Police tested the DNA of men she knew, but none matched. But then came along Christopher Tapp, who knew Dodge. His DNA did not match either. After 28 hours of interrogation over 23 days, Tapp confessed to being there when she was killed. He said that others stabbed her. One of the men, he said, was named Mike, though he didn't know his last name. Tapp was convicted of killing Dodge. But officially, the case was still open because Tapp's DNA didn't match that found at the crime scene.

In 2014 police searched a public database owned by Ancestry.com. The goal was to find a close match, perhaps a family member to the alleged killer, through a process called familial searching. It was just this kind of search of familial DNA in a public database, Gedmatch.com, that led to the arrest last April of Joseph DeAngelo, the man suspected of being the Golden State Killer responsible for at least 12 murders and 50 rapes.

In the Dodge case, police found a partial match. Armed with a warrant, police got Ancestry.com to reveal the name of the man behind the DNA sample. His name was Michael Usry Sr., and he had a son, Michael. Police wondered if Usry Jr. could be the "Mike" that Tapp told them about.

Usry Jr. is a filmmaker with a short film titled "Murderabilia." Given the subject of Usry's film, along with the fact he'd been through Idaho Falls at one point in his life, police thought they had the killer. However, Usry Jr. had nothing to do with the 1996 death of Dodge and was officially cleared. Still, his story raises questions about what happens when police use publicly available DNA databases to solve cases - and what goes on when an innocent man is tagged as a suspect. Usry Jr. has now joined with Dodge's mother to search for the killer. They also believe Tapp is innocent.

48 HOURS: "Storm of Suspicion" - In an encore presentation at 10:00 PM, ET/PT, Maureen Maher and 48 HOURS' investigate the disappearance of a young mother of two who vanished a day before Hurricane Harvey hit the region. 48 HOURS had unprecedented access to the Chambers County command center in Baytown, Texas, a suburb of Houston, as investigators searched for Crystal McDowell. The 37-year-old realtor was last seen leaving a boyfriend's home on the morning of August 25, 2017, to pick up her two children who were staying with her ex-husband, Steve McDowell. But McDowell told sheriff's deputies that she never arrived. An uncle and other family members reported Crystal missing.

In the days that followed, Harvey dumped historic levels of rain on Texas, tying up emergency services, closing roads, flooding homes and pressed all available first responders into helping thousands of displaced Texans. Meanwhile, a taskforce, including Texas Rangers, deputies, District Attorney Cheryl Lieck and Sheriff Brian Hawthorne, continued their investigation into Crystal's disappearance. They had plenty of people to speak with, starting with her ex-husband, Steve McDowell; her new boyfriend, Paul Hargrave; and her uncle, Jeff Walters. But there were others. 48 HOURS: "Storm of Suspicion" follows the team as they pieced together the last known moments of McDowell's life, revealed how police found her body, and included the shocking arrest that left family members stunned.
