They/he probably scared the old lady to death. LiterallyThe ransom demands were haphazard and not constructed well, I think if more than one person was involved that with more input the communication and procedures would have been presented better. Going on three weeks the chance of someone in a group getting nervous and making a mistake would increase, a single person could isolate a lot easier. The longer this goes on makes me think that whatever the plan was it did not play out as expected.
