Role in the post-conviction critique
Helen Shannon’s collaboration with Prof. Geoff Chase concluded that, on the Crown’s theory of administration (a small “spike” of insulin into a TPN bag), the reported insulin values for Babies F and L would have required quantities of insulin far in excess of what the alleged mechanism could deliver. The reported numbers are on the order of values seen in adult attempted-suicide presentations — not the quantities the prosecution theory required.
Why this biography is on the site
The Chase & Shannon physiological-modelling analysis is one strand of the wider insulin-evidence critique now before the CCRC. It engages the prosecution theory at its mechanism: independently of the immunoassay-interference, hook-effect, sample-handling and forensic-laboratory-standard grounds, the Crown’s numbers do not make physiological sense on the Crown’s own mechanism.
