The chef was also essential to the running of the camp.
Problem comes when being an "essential" book keeper, who repeatedly tried to be transferred to the front lines, doesn't magically make someone complicate in killing.
Nothing was presented at the trial to show his actions caused, led to or facilitated the killings. They declared him cataloguing items after they had been taken from prisoners as somehow facilitating deaths.
What they convicted him on was a broad declaration that simply being essential and knowing what was going on makes you complicit in unrelated war crimes. They didn't convict him of any actual war crimes, since nothing he did was a war crime. Which is why he was acquitted of war crimes during the 70's.
This sweeping generalization law means that the military chef is "complicit" in the murders of Jews.
Worse still, he tried to be reassigned to the front lines repeatedly, making the claim he knowingly took part in it redundant.
The entire trial is a mockery of the justice system. Broadly stretching laws so they can politically claim they prosecuted a Nazi. Even though he did not commit a single war crime.

This pretty much.

It appears they have in fact spent time and money chasing this guy.
