Bribery through housing loans?

Given the on going bribery case with Greg Opinski and former mayor of Los Banos Tommy Jones. Would it be possible bribery has been a on going problem? Below is a property deed associated with OP DEV INC. Which loaned nearly 300,000 dollars to a Sheriff Gerald Dover.

Whether or not its a bribe or not I could never tell. Another person of interest would be a Luiz Dorothy (Dorothy Broughton Luiz)  who is possibly in relation to a Kimberly and Albert Flores.

Keep in mind the Dovers own Envy Fine Clothing, which could be a money laundering service.
