"Concern escalated dramatically when Simon’s phone was switched off after a call to his girlfriend, who lives in Boston. "
I think it's fair to assume that as his girlfriend lives in Boston, and Robinson spends much of his time in Boston, Lincs., that the Boston being talked about is not in America!
His "notices" are saying that he is 6' 2" because he is British, and in Britain people measure themselves in feet and inches! (But perhaps it would have been appropriate to put his height in cm in brackets beside it.)
