The case, long cold with no conclusive leads, finally sees progress when new DNA testing of the dress Karla was wearing during the attack points to Glenn McCurley Jr., a local father of two. Detectives Jeff Bennett and Leah Wagner approach McCurley for a DNA swab, which reveals a match with the DNA found at the crime scene.

Notable Quote:

• Karla Walker's Brother, Jim Walker: "He showed her a picture of Carla to Glenn, said he didn't recognize her."

3. Glenn McCurley Jr.'s Interrogation and Confession

Timestamp: [07:00] - [16:37]

Initially denying any involvement, Glenn McCurley Jr. becomes emotional during his interrogation. Under gentle but persistent questioning by Detectives Bennett and Wagner, he admits to raping Karla but initially denies killing her. Further probing leads McCurley to confess to strangling Karla, especially after being confronted with inconsistencies in his statements and the overwhelming DNA evidence.

Notable Quotes:

• Glenn McCurley Jr.: "I did go to the bowling alley parking lot that night... I pulled her out of the car and saved her from an attack."

4. Uncovering a Serial Killer

As the investigation deepens, detectives discover that McCurley may be responsible for multiple murders beyond Karla's case. Previous victims, such as Becky Martin, show striking similarities in their abductions and murders, including the method of strangulation and the location where their bodies were found. The revelation that McCurley's DNA matches samples from other unsolved cases suggests he may be a serial killer who evaded detection for decades.

Notable Quote:

• Jim Walker: "We have a strong suspicion that Glenn's responsible for not just several murders in our city, but he was also a truck driver. He had a route from Fort Worth out to California and back."

5. The Trial: Challenges and New DNA Technology

Timestamp: [26:33] - [43:30]

Despite McCurley's confession, he pleads not guilty, prompting a trial that hinges on the admissibility and persuasiveness of the new DNA evidence provided by Othram. The trial is set to be a landmark case as it tests the efficacy of Othram's forensic genetic genealogy in court. The courtroom dynamics are intense, with emotional testimonies from both families and the introduction of McCurley's confession tape as key evidence.

Notable Quote:

• Aylin Lance Lesser: "It will be the first time that this new DNA technology that Othram has developed will be tested in a court case."
