The bindings on all the victims were around equal length, give or take a few centimetres. I don't really get why you linked us to autopsy photos of Stevie with his face smashed up, etc.
That's not going to help with working out the shoe laces, and isn't really very respectful to the victims, in fact that's even more disrepectful than the opening scenes of the PL movies.
So glad I didn't click the link.
