This is a truly bizarre story. Why would someone that old sit on all of that art? He will be dead soon so it makes no sense. Why would someone try to smuggle cash on a train? Someone had to be tipped off!
Sitting on the art makes sense in that the man was probably trying to keep a low profile. As to smuggling cash on a train you need to read up on how the Europeans are doing systematic searches for people carrying cash around Europe these days.
