My question involves criminal law for the state of: Louisiana

I work as a front desk clerk for a hotel , I came into my shift and counted my till (which is unsecured ... Basically just a drawer with no lock ) and not attached to a Pos system , I checked the communications log . Not the night auditor but the previous pm shift notated the register would be short $100 and something , it was only short $12. Anyways the next morning I get a text from the GM asking did I see the deposit from the previous night in the drawer (that was suppose to be dropped ) I told him no , because there was not a deposit in the till . Hours go by , and he says the night auditor and the previous pm shift claim they seen the deposit in the drawer , let's rewind , when I came to work the night auditor said nothing about there being a deposit from the previous shift that needed to be dropped , nor was there any documentation saying so. The GM runs the camera from my shift and says he seen me pick up an envelope and then set it back inside the drawer , and he assumed that was the undropped deposit . Like I told him if I did pick it up and sit if back down, it was because it was a plain , unfilled out and empty . Now he is accusing me of stealing the deposit that should have been dropped by the two previous shifts and asked me to pay it back or he was going to prosecute . I told him do whatever he needs to because I did not see the deposit nor did l take it . Should I get a lawyer and when the police come talk to me should I answer anything or request counsel right off back since I am being accused ?
