Nope, w-2 is just someone that the driver sent a picture of 2 bundles of money to. The person who went to the bank is only described as "the employee" that person has not been assigned a Witness number at the time of the charging documents. I personally believe that "the employee" who got the cash at the Hyattsville bank branch is the accountant. But he is definitely not W-2.
I wonder if the "driver" unintentionally made people think his wealthy employer had so much money he probably had about 100K in a home safe or had really expensive jewelry worth that or more in a home safe. All speculation on the part of the "show-off" driver. The info. reached the wrong ears and this was all supposed to be nothing but a home robbery. I wouldn't be surprised if they wore masks, but then when the money was not in the house, they got tired of the masks which led to having to kill anyone who could identify them. They were torturing the boy thinking Mr. S would come clean and give them the location of the house "safe". It just all went wrong, maybe.
