LaVar better hope that all Alan was doing was embezzling money. If he had any other illegal activity going on, LaVar would look guilty too for looking the other way this badly. I know of cases like this where people had to use low IQ as a legal defense and based on the details out there so far, LaVar might be legit retarded.
If Lonzo has a financial advisor, why did Alan have access to these accounts? As an ex-con, he never should have been there in the first place but if they did trust him to help run the business, he should not have had access to cash. Who would he need to pay outside of approved vendors? And you can set those up for ACH payments and/or do weekly check runs. It takes 2 minutes to review a payment run for reasonableness each week.
Alan may be a thief who betrayed their trust but its equally alarming that LaVar has absolutely no clue what he's doing.
