If brother was diddling in any way with an elderly person's business then APS would investigate. The issue is not the money, but the brother doing anything with the funds if he were not a POA appointed when parent was competent and using the funds for other than that allowed by POA document.
POA does not need to be co-owner of an account to handle the money in the account, but being co-owner gives him the funds upon her death. Too many people do not understand POA verses ownership access.
OP is looking at several thousand to have an attorney review the situation. It is unlikely that any pre-death actions can be undone easily - or cheaply - unless brother is cooperative.
The whole problem is having a trustworthy, organized, detail oriented person as POA and executor.
