My employer thinks I stole $1.5k

Location: North Georgia

My wife recently left me, and I am working out my notice at my job. I am a restaurant manager, and I had forgotten to deposit a few bank deposits for work at the bank on my way home in the night drop. Today at the end of my shift the owner, general manager, and office manager met with me in a side room and basically told me that money was missing from what was supposed to be deposited, and they know I stole it. In shock, I realized with everything going on, I forgot to take them to the bank and they were still sitting in my car. I tell them that, and the general manager escorts me to my car to retrieve them. When we take them back inside, the office manager goes through the envelopes and counts each one. After she’s done counting, she says there’s still $1,500 missing. I insist that she recount the money because I didn’t touch any of it, but the general manager tells me I have no control over this situation. He tells me that I either bring the money tomorrow by 3pm, or he’s calling the cops. He then kicks me off the property under threat of calling the cops.

I immediately drive right down the road to the gas station and start tearing apart my car to try and find any missing deposit that may be in there. I did it again when I got home. I am sure there’s no missing deposit in my car. I didn’t steal the money from them, and I don’t have $1,500 to pay them. I know I was neglegent in leaving the deposits in my car, but I would never steal any money. Is there anything I can do, or am I screwed?
