Editing Bob Crane (section)

===Investigation===
Scottsdale police had no homicide division in 1978, so it was ill-equipped to handle such a high-profile murder investigation. The crime scene yielded few clues; no evidence was found of forced entry, and nothing of value was missing. Detectives examined Crane's extensive videotape collection, which led them to Carpenter, who had flown to [[Phoenix, Arizona|Phoenix]] on June 25 to spend a few days with Crane. Carpenter's rental car was impounded and searched. Several blood smears were found that matched Crane's blood type; no one else of that blood type was known to have been in the car, including Carpenter. [[DNA testing]] was not yet available, and the [[Maricopa County, Arizona|Maricopa County]] District Attorney declined to file charges.<ref name=two/>

In 1990, Scottsdale police investigator Barry Vassall and Maricopa County Attorney's Office investigator Jim Raines<ref name="three" /> re-examined the evidence from 1978 and persuaded the county attorney to reopen the case.<ref name="bulletin">{{Cite news |date=March 12, 1993 |title=Crane case to go forward |work=The Bulletin |url=https://news.google.com/newspapers?id=e45TAAAAIBAJ&pg=3759,5008597&dq=bob+crane+john+henry+carpenter+sex&hl=en |access-date=December 15, 2012}}</ref> DNA testing was inconclusive on the blood found in Carpenter's rental car, but Raines did discover an evidence photograph of the car's interior that appeared to show a piece of brain tissue. The actual tissue samples recovered from the car had been lost, but an Arizona judge ruled that the new evidence was admissible.<ref name=bulletin/> In June 1992, Carpenter was arrested and charged with Crane's murder.<ref>{{Cite web |date=May 8, 2008 |title=How did Bob Crane die, anyway? |url=http://www.straightdope.com/mailbag/mbobcrane.html |access-date=December 15, 2012 |publisher=straightdope.com}}</ref><ref>{{Cite news |last=Balazs |first=Diana |date=September 12, 1998 |title=Suspect in killing of 'Hogan's Heroes' actor Bob Crane |page=A–12 |work=Pittsburgh Post-Gazette |url=https://news.google.com/newspapers?id=XoRIAAAAIBAJ&pg=5427,579515&dq=bob+crane+john+henry+carpenter+sex&hl=en |access-date=December 15, 2012}}</ref>
