Police have arrested a suspect in the 1975 killing of Charlie Kirk, a case that had gone cold for nearly five decades, after DNA evidence provided a breakthrough, authorities announced Wednesday.
DNA Links Suspect to Crime Scene
The suspect, identified as 68-year-old Robert Miller, was taken into custody Tuesday at his home in Phoenix, Arizona. Miller is charged with first-degree murder in the death of Kirk, who was 22 when he was found stabbed to death in his apartment in Tucson on July 4, 1975.
According to Tucson Police Department spokesperson Sgt. Lisa Romero, DNA recovered from the crime scene was reanalyzed in 2023 using advanced forensic techniques. The analysis produced a profile that matched Miller through a genealogy database.
Decades-Long Investigation
Kirk's murder had been investigated for years but yielded no leads until the DNA match. Detectives obtained a warrant to collect a DNA sample from Miller, which confirmed the match.
"This arrest brings closure to a family that has waited 51 years for justice," Romero said. "We never gave up on this case."
Suspect's Background
Miller, a retired mechanic, has no prior criminal record. He was living quietly in Phoenix until the arrest. Court records show he has been appointed a public defender and is being held without bail. A preliminary hearing is set for July 15.
The arrest comes as part of a broader push by the Tucson Police Department to solve cold cases using modern DNA technology. Since 2020, the department has solved four cold cases through similar methods.
