Maybe there is a way that Findley's family can sue White's family and anything they win from their suit will go to the officer's family.
But see, there's a flaw.
White was a criminal awaiting trial.. he was killed while awaiting trial and in so 'denied his civil rights'. That's a multi-million dollar award just waiting to happen
Findley, on the other hand, was a cop on duty, he hasn't been denied anything, or at least not his civil rights. He wasn't awaiting trial for murder just waiting for the end of his shift. That's worth whatever his county life insurance was good for, and any owed pay, and MAYBE the cost of a funeral.
Nothing his family can sue anyone for, whereas White's family has the county Sherrif, the Correctional Facilitiy, the County, the State.. They have ALL kinds of people they can sue.
Now White's family maybe able to sue Findley's family for the proceeds of his life insurance and his owed backpay too, yanno since it was Findley's dying that led to their child getting arrested and being denied his civil rights.
