Obsessed with teenage babysitter JC, Christopher Dawson murdered his wife Lyn in terror of losing what he so deeply desired. That was the powerful thrust of a meticulous and forensic closing address, delivered over two days by Crown prosecutor Craig Everson SC. Everson said Dawson made four separate plans to escape his marriage before ultimately killing Lyn, disposing of her body and racing to South West Rocks to collect JC and install her in the family home, wearing Lyn's clothes and her rings.This is the first of two episodes focusing on the closing submissions by each side.
