a built in opportunity. here s how. the a-team wanted to know if heather or ethan forged kate s $4,500 check. but they needed original handwriting samples. we determine what was on the check that we needed comparison samples to. and we had numbers, obviously, on a check. keith morrison: then, the a-team helped ethan s landlord prepare ious that contained the needed numbers and letters. and when heather and ethan signed the documents agreeing to pay the rent in installments, they were giving the team the very samples that could prove they forged kate s check. the team took the handwriting to their waiting expert, mickey dawson the man who set up the state police handwriting lab. the question was simple, did heather, and or ethan, forge that check from kate the one ethan tried to cash? immediately, that day, our handwriting document examiners said, that s them. no question about it. keith morrison: so, if ethan and heather forged a check from kate, what else did they do?
