@Stoneshop - It's not the brand/model of the laptop but the existence of a set of files on the laptop. One other idea is the hard drive could be copied onto other. But there are a couple of problems with this case. Laptops have serial numbers and probably company inventory numbers assigned. Someone should be checking the these numbers immediately when the equipment is turned in. Why wasn't his account cancelled on his last day? The technical skills required are fairly common even if I personally suck at pl/sql and they are not that difficult to learn.
