Sounds like and inside job. When I first got in the car biz, I worked for a Mitsubishi dealer. Over the weekend, our lot got hit. 16 Eclipse wheels were missing, and a bunch of stereos.
My boss calls me into the office, and wants to know what I was doing over the weekend.
I basically told him to go f#*!#k himself, and that just because I was a long hair, did not make me a thief. He checked both of my cars stereo's over the next few days, He tried to be sneaky about it, but our parking area was right outside the shop, and I watched him look in both cars. I quit that job a few days later, it was a crappy job anyhow.
My boss's nephew had also worked there. Wouldn't you know it, a couple of weeks later, they find a Mitsubishi stereo in the kids bronco.
A couple of years later, my old boss comes into my shop trying to sell me amway. I advised him that it would be wise to leave the premises, that was a feel good day.
The wood blocks are on old school way to steal wheels, your first loosen the lug nuts, then you set the blocks up under the axles/ control arms, and let the air out of the tires, and slide the wheels right off, no jack needed, that is exactly how they stole the wheels from our lot.
