here's a list which i have come up with for finding the pink slips in the bonus markers. according to gamewinners.com, the first pink slip is the 2nd ? marker, then it goes to the 3rd ? marker for #14 and then returns to the 1st ? marker for #13 and repeats itself throughout. so the pinkslip order should go like this:
Blacklist #15 Pink Slip: 2nd ? marker
Blacklist #14 Pink Slip: 3rd ? marker
Blacklist #13 Pink Slip: 1st ? marker
Blacklist #12 Pink Slip: 2nd ? marker
Blacklist #11 Pink Slip: 3rd ? marker
