Family members identified a pendant from Carnahan, and DNA tests confirmed her identity. However, police still did not know who killed her until the results from an unrelated 1994 backlogged rape kit from Washington recently came back, authorities said. "The rape case was deemed 'unprovable' in 1994 and the kit remained untested until 2023," the release explains. Harold Carpenter. El Dorado County District Attorney/facebook Once the kit was tested and uploaded to the FBI's DNA database, authorities "found that the DNA collected from the Washington victim also matched the DNA evidence collected from Patricia Carnahan, identifying the suspect in her murder as Harold Carpenter," states the release. Authorities say the Washington rape case has since been dropped as the statute of limitations has expired and the victim is now dead, but Carnahan's murder case will move forward. "Cases like this illustrate the need to test every sexual assault kit and get their DNA profiles loaded into the federal database," Washington State Attorney General Bob Ferguson said in a statement. "Every untested kit could be a potential break in a cold case. Hard work and cross-state collaboration made this case successful. I'm grateful for the hard work from law enforcement to pursue justice in this case," Ferguson said.
