Editing Bob Crane (section)

===Later DNA testing===
In November 2016, the Maricopa County Attorney's Office permitted Phoenix television reporter John Hook to submit the 1978 blood samples from Carpenter's rental car for retesting, using a more advanced DNA technique than the one used in 1990.<ref>{{Cite magazine |last=Kimball |first=Lindsay |date=November 15, 2016 |title=New DNA Evidence Proves ''Hogan's Heroes'' Star Bob Crane's Murderer Is Still Unknown |url=http://people.com/crime/bob-crane-murder-new-dna-results/ |magazine=People |access-date=November 16, 2016}}</ref> Two sequences were identified, one from an unknown male, and the other too degraded to reach a conclusion. 

This testing consumed all of the remaining DNA from the rental car, making further tests impossible. Hook's investigation turned up two blood vials, samples from Crane and Carpenter, located in evidence storage at the Maricopa County Attorney's Office. Carpenter voluntarily gave a sample to Scottsdale Police when he was questioned in 1978. Crane's blood vial was recovered during his autopsy the day after the murder. Both were used as comparison samples for Hook's DNA tests on the blood stains found in Carpenter's rental car.<ref>{{Cite web |date=November 15, 2016 |title='Hogan's Heroes' star Bob Crane's murder still a mystery despite new DNA tests |url=https://www.foxnews.com/entertainment/hogans-heroes-star-bob-cranes-murder-still-a-mystery-despite-new-dna-tests |access-date=November 16, 2016 |publisher=FoxNews.com}}</ref>
