In December of 2008, a 74-year-old Caucasian male named Richard Cline was found deceased in his Las Vegas residence, marking the beginning of a homicide investigation that would span more than a decade. The discovery was made on December 19, 2008, in the 5800 block of West Harmon Avenue. Initially, authorities treated it as a suspicious death, but the circumstances surrounding Cline's death soon pointed toward a violent struggle.
An autopsy conducted by the Clark County coroner's office
confirmed the violent nature of the death. The cause was determined to be a combination of neck compression and blunt force trauma, indicating that Cline had been strangled and beaten. Despite the clear evidence of a homicide, the initial investigation failed to identify a suspect, and with all leads exhausted, the case eventually went cold.
For years, the case remained unsolved, one of many cold cases in the Las Vegas Metropolitan Police Department's files. However, in a significant breakthrough, cold case investigators decided to re-examine the evidence in November 2019. DNA evidence collected from the scene in 2008 was resubmitted for testing using newer, more advanced techniques. This led to a crucial discovery: a DNA match that identified a potential suspect.
The DNA profile belonged to Quincy Cook, who was 44 years old at the time of his identification in the Cline case. Cook was already incarcerated at the Clark County Detention Center on unrelated charges. In March 2020, more than eleven years after Richard Cline's death, Quincy Cook was rebooked on charges of murder and burglary in connection with the 2008 cold case. This arrest brought a long-awaited development in the quest for justice for the death of Richard Cline.
