Going back to the increase of the reward by $25 million to $35 million by JS in 2022, five years after the deaths of Honey and Barry.
In my world $10 million, even in Canadian dollars is a a substantial sum. By raising it by another $25 million, the case surely got media attention. JS likely increased the reward because he wanted to entice someone to talk and solve the crime.
Why has nobody come forward with relevant information? (I am assuming nobody has.) People who know for example who the Night Walker is, are afraid to talk, or do not know there is a reward.
What if the Night Walker is dead? Nobody to identify, nobody to charge, no reward to be paid.
