It seems that at this point in time, the van is the only evidence that circumstantially links KR to the murder. I've collected a few links below. Perhaps Sgt Arns is one of the final prosecution witnesses to be called to testify tomorrow.
".......A forensic police expert will testify that a "bloodletting event" took place in Rubletz' van and Newman's DNA was discovered on the front passenger seat. Parker told jurors the van shows evidence of a "botched cleanup."..."

"......On Wednesday morning, Det. Wayne Birks finished his testimony, which began the day before.
Birks was also involved in the investigation when Newman was still considered a missing person. He interviewed Rubletz several times.
At the time, Newman was still considered a missing person, and Birks said he did not have the authority to seize the van.
In cross-examination,
Miller pointed out that Rubletz allowed Birks to look inside his van and that the officer did not see any blood or staining.
The Crown has already indicated that forensic testing showed a "bloodletting" event took place in the vehicle and that Newman's DNA was found inside..."

"....Rubletz later that day went to Lamberts home to return some materials he had stored in the back of
his mothers van, which the accused was using during that time period...."

".....According to the prosecution's theory, Newman's death was a "crime of passion" that took place the night of March 10, 2015. Prosecutors Shane Parker and Tom Spark say
evidence will show Rubletz killed Newman in his van and then dumped her body north of Calgary.
After Newman's body was discovered in May 2015 in a ditch near Balzac, Rubletz's grandmother, mother and stepfather took the van to
a scrap yard, but police were able to intercept it and run tests, jurors have heard.
The van driven by Kevin Rubletz was
found at a pick-and-pull lot after Jessica Newman's body was discovered two months after she disappeared. (Court exhibit )

Note the difference in reporting context, above and below. A pick and pull lot at an auto wreckers, where parts are sold and stripped directly from old vehicles, is very common but the Sun makes it appear the deliberate destruction of evidence was the intent.
".......The day after Newmans body was found, relatives of the accused took his van to a wrecking yard.
But before the vehicle was crushed, officers were able to seize and inspect it..."

".....Adeagbo agreed with Miller that Newman was stabbed on multiple parts of her body but mostly on her left side.
He agreed with Parker the dozens of wounds could have been inflicted with Newman for the most part being seated in a bucket seat of a vehicle with her killer attacking from the right side."

".......Among the witnesses jurors will hear from, Parker said, is bloodstain pattern analyst Sgt. Jodi Arns.
She believes inside the van there was a blood-letting, the prosecutor said.
Newmans DNA was found in the vehicle, including on the underside of the fabric of the passenger side seat, which had been gouged.
This the Crown will argue, is circumstantial evidence inferring a botched cleanup, he said....."

I wonder how it would ever be possible to clean up the inside of a van where a murder had occurred involving 75 stab wounds so well that the initial officer investigating her disappearance wouldn't have noticed? How would one clean the inside of a seat, if it were gouged during a stabbing? As for JRNs DNA in the van, that's certainly not unusual considering all. Is this evidence that will convict, guilt beyond a reasonable doubt?
