Just how? I understand how you can start a relationship online and it become serious but all those years, no video calls, the utter absurdity of witness protection - even a rudimentary search would tell you there’s no way he’d be communicating with you whilst in the plan.
A British man shot in NY would make the news - maybe not national but local and it would be Google-able
I just can’t get my head around how you could be so fooled.
