All wards require two signatures of the bishopric (comprised of Bishop and his two counsellors) for any transaction. This ward has sufficient numbers to require a separate clerk for general matters (ward Clerk), finance matters (ward Finance Clerk), and membership matters (ward Membership Clerk). The only ones with access to finances in the ward are the Finance Clerk and Bishop. The ward Executive Secretary ONLY handles scheduling and appointments for the Bishop. The ward Clerk takes notes at meetings. There's no possible way CD as ward Executive Secretary would have had access to finances without other eyes on those matters.
Additionally, all wards are independently audited at least yearly during the Ward Conference process (ours happened in January 2020). Ward audit was approved and accepted.
I can appreciate the concern that POIs who have exhibited strange, unanswered behavior, and even alleged activities that are apparently criminal. It would be of greater concern if the issues you bring up could be possibly true. However, I'm confident that this was not the case. I appreciate the concerns as such would 1) implicate a further spread of influence, and 2) taint those innocents who would of necessity be involved in such activity. Thankfully, again, based on the points I've raised, I am confident that such activities did not occur while CD was ward Executive Secretary.
