The sickening letter sent by Stewart Blackburn
By Cara Sulieman & Paul Thornton
A LETTER sent to the parents of tragic Jessica McCagh by fire-ball killer Stewart Blackburn after her murder shows his obsession with death, a handwriting expert has revealed.
Sick Blackburn, 18, penned a poison note from his cell at HMP Perth before being convicted of dousing pretty Jessica in petrol and setting her on fire.
Now top handwriting expert Barbara Weaver has revealed that his child-like writing shows it was just a matter of time before the youth lashed out.
Barabara, from from the Cambridge School of Graphology, said his letter proved he was prone to lash out and likely to have fantasies about the death and a desire to punish.
