To make matters worse the arms are secured by two leather straps with the arms crossed in front before they are placed in the shackles. The leather straps are also secured by padlocks.
As the icing on the cake Roslyn also had a crotch strap attached to the belt that fastened at the rear with yet another lock.
In the original Chrysalis Escape the escape artist has his (or indeed her) head placed inside a canvas bag. Although this restricted the escape artists breathing it did still allow the escape artist to breath.
So, Roslyn replaced the canvas bag with a clear plastic one. Having only one minute of air inside the bag meant that time was immediately against him. If that wasn't enough the bag was held in place with a metal collar that was locked in place with a padlock.
Most escape artists would stop there, and they'd be right to do so, but Roslyn wanted to add one final touch... an airtight BODY BAG.
In the original Chrysalis the escape artist was placed inside a large canvas bag. This did a few things; first it restricted the escape artists movement, secondly if the escape artist got in to trouble during the escape no-one would know until it was too late and finally the air inside the bag would heat up during the escape to deadly levels.
Again, Roslyn wanted to change the use of the canvas bag to something that; one people would recognise and two would add an extra element of danger not found in the original escape.
The body bag did just that.
Due to nature of its intended use a body bag is fully airtight. It is also water tight, which means as it heats up none of the hot air or moisture can get out.
There is only 8 minutes of air inside the bodybag, so even after escaping the head bag suffocation is still a major possibility.
Roslyn Walker managed to escape the Chrysalis in just under 10 minutes.
