Disgraced architect Graham Dwyer is said to be furious that the public have stopped writing him letters.
The avid writer is said to be sending at least 12 letters a week to various people and body-groups in an effort to stay connected to the outside world from his prison cell.
Dwyer is said to be particularly perturbed with not being able to attend his 25th school reunion, he was allegedly an organiser of the 21st reunion.
A model airplane enthusiast, his fellow club members are said to have cut all contact with the 44-yr-old since his conviction.
A court eventually found that Elaine O’Hara was murdered by the sick Dwyer on August 22, 2013.
