Employee Liability

I left my former employer in mid-October after working there approximately 9 months. It was a small inventory service which while not entirely relevant was very unsound ethically. I just got a call from my father that a detective is looking for me as my ex-employer is stating I stole $125,000 worth of equipment. Upon my leaving I left a company van parked in a business center parking lot with equipment (Adding machines, printers, laptops), locked it, put the key in the gas compartment, called them and told them where to pick it up (otherwise they wanted me to drive it 5 hours to them, ha). Anyway, they say that when they picked up the van there was no equipment in it. As a side note this equipment is 100% worthless to anyone that isn't working currently for the company as it is safeguarded with a 30 day license that needs to be renewed from the company electronically. No charges have been made yet, I left a message for the detective and am waiting on a return call. As another side note, when I came on board with the company you do sign a waiver to be financially responsible for any equipment in your possesion. I was DM for several offices, and the equipment tracking was horrible at best, which is how I am sure it comes to pass that I am on record for a lot of it. They also never paid out my final paycheck... My friend worked for me locally in the Columbia SC office, and quit at the same time, she did witness me locking the equipment in the van. I guess I understand how they can try and find me financially liable, but I would think this would be covered under insurance for the van for someone else stealing it wouldnt it? Is there any way I am criminally liable for missing equipment? Please note that the detective is in Atlanta, where my boss worked out of. At the time I worked in the Carolinas, I now live in Florida.
