A breakthrough in DNA technology has led to the arrest of a suspect in a 2008 cold case murder in Grand Prairie, Texas. The case of 45-year-old Raymond Hernandez, who was stabbed multiple times in his home, went cold after DNA evidence found at the scene did not generate a match in the national database. However, in 2022, the DNA sample was found to be a match in two sexual assault cases in Fort Worth, leading police to 44-year-old Jerry Lee Gardner. Gardner was arrested at his home in East Texas on October 4, 2024, and charged with capital murder.
Grand Prairie Police Sgt. Tracy Hinson credited new forensic genetic genealogy technology for solving the case, describing it as a game changer for law enforcement. The technology allowed investigators to create a sketch of the suspect’s physical appearance in 2017, but it wasn’t until the DNA match in Fort Worth cases that Gardner was identified as the suspect in Hernandez’s murder.
Hinson emphasized the importance of forensic genetic genealogy in solving cold cases and expressed optimism for its future use in law enforcement. While Gardner has not been charged in connection to the sexual assault cases in Fort Worth, detectives continue to investigate a motive for Hernandez’s murder.
The arrest of Gardner highlights the effectiveness of DNA technology in cracking cold cases and bringing justice to victims and their families. The Grand Prairie Police Department, with the help of the Texas Rangers, worked diligently to solve the case, signaling a new era of advancements in solving crimes using DNA evidence.
