Wow, great observation. Yes, the killer threw diesel fuel on the car of victims Cathy Thomas & Rebecca Dowski. I'm trying to find a link that mentions it, but most of them are links to blogs, You Tube videos and podcasts.
Here's one from Coastal Virginia Magazine that mentions diesel fuel. ETA: The offender's hair was found in the hand of Cathy Thomas, so there has been DNA from that offender to test. One of the articles about solving the other murder mentioned the FBI will test it.
America's narrowest national park, the Colonial Parkway, connects the southern edge of Jamestown to Yorktown via a winding 23-mile route that cuts thro ...

All afternoon I've been youtubing all kinds of past videos on the CP case & victims.
If a diesel boat can link Cathy Thomas & Rebecca Dowski to the recently announced individual, perhaps a revisit of the DNA would be possible in two other cases as well:
CP Linked Murders:
1) Rebecca Dowski and Cathy Thomas:
* Vehicle & Victims doused with diesel fuel and car pushed over embankment
* Clump of hair found in Cathy's hand - can this be DNA tested against
Alan Wilmer Sr or Keith Wilmer?
* Numerous partial & full fingerprints on vehcle that matched no offenders in the system
- Did the DENNI WADE,
Alan Wilmer Sr's boat run on diesel?
- Did
Alan's brother,
Keith Wilmer's boat run on diesel ... or did the DENNI WADE belong to both of them?
- Were fingerprints obtained from
Alan Wilmer Sr's body or just his DNA for identifying him? Would it be possible to obtain them now as we know he had no record prior to his death? Or
Keith Wilmer's?
-
Keith Wilmer was an early suspect in the 1985 murder of
Mary Harding.
- Keith Wilmer's polygraph on the Harding case came back "inconclusive".

2) David Knobling and Robin Edwards (Confirmed Killer: Alan Wilmer Sr via DNA)
Virginia State Police identified Alan Wilmer Sr. as a suspect in the 1987 double murder of David Knobling and Robin Edwards, and the 1989 murder of Teresa Howell.

“If not for Wilmer’s death, charges would be filed against him in connection with the three homicides,” said VSP spokesperson Corinne Geller.
3) Cassandra Hailey and Richard Call
* Bodies never recovered
* Car staged like other CP murders
*
2 empty beer cans found at scene of car (as per youtube video "The Colonial Parkway Murders - Revisiting The Crime Scenes" at 12minute, 9 second mark of video).
- Have DNA tests ever been run on these beer cans?
- If not, are the cans still available in evidence for testing purposes?
*
Alan Wilmer Sr identified as an early Prime Suspect in these murders, was surveilled, but passed a polygraph. I take it from the statement that he became a suspect because of his distinctive truck and the plate. Did someone tip-in his vehicle as being near to or at the crime scene?
Could Alan Wilmer Sr., who died in December 2017, be responsible for another “Colonial Parkway Murder?”

In an interview for the book, Wells told Pardoe one thing that caught their eye was Wilmer’s unique looking 1966 Dodge Fargo with the license plate, EM-RAW. On Page 205 in Pardoe’s book, he refers to the pickup truck and the license plate EM-RAW, which was brought up at Monday’s news conference. He abbreviates the license plate and notes it, because Wilmer was given a polygraph test — which he passed.
4) Annamaria Phelps and Daniel Lauer
5) Teresa Howell, then 29, in Hampton (Confirmed Killer: Alan Wilmer Sr via DNA)
Virginia State Police identified Alan Wilmer Sr. as a suspect in the 1987 double murder of David Knobling and Robin Edwards, and the 1989 murder of Teresa Howell.

“If not for Wilmer’s death, charges would be filed against him in connection with the three homicides,” said VSP spokesperson Corinne Geller.
Possible Victims:
Mike Margaret and Donna Hall
* Both victims had been stabbed and their throats slit
* Car left with items intact, keys in the ignition in the staged scene
* Car left and staged in wooded area off scenic trail
* Modus operendi very similar to the Colonial Parkway series
Mary Keyser Harding
*
Keith Wilmer, the brother of some CP Parkway murders' confirmed killer Alan Wilmer Sr was an early suspect in the 1985 murder of
Mary Harding.
* Keith Wilmer's polygraph on the Harding case came back "inconclusive".
(Link to lengthy article with details about Keith and the murder of Mary Harding: A Murder on the Rappahannock River - Washingtonian)
* Mary was found in the river naked.
... A rope around her neck was tied to a large cinder block. A heavy chain was secured to the rope, too, its other end wrapped around her right leg.
Riley recognized the equipment—you’d find it on the boat of many watermen.
Photos of the chain & hook equipment used to tie her down is included in the article.
*
the documents showed that two of the men Riley and the FBI were initially interested in each kept boats near where the remains were found. One of them, Keith Wilmer, was the husband of one of Mary’s colleagues at the Bank of Lancaster, the waterman whose polygraph had been inconclusive.
Part One The sun was just beginning to fade when David Riley pulled up to the little house off Route 354. The Virginia State Police detective got out of his unmarked Ford Fairmont and took in the setting of the mystery that had brought him here—a low-slung home shrouded in trees and underbrush...

I may be wrong, but isn't there also something out there that LE or the FBI believed that there may have been TWO people present at some of the crime scenes and that there was evidence to show such?
