According to The Guardian, Prosecutor Duncan Atkinson QC told the court there were  “significant similarities” between the two women’s death.
 
The prosecutor argued that both women were treated violently by Mr Trigg. 
 
“Inquiries have revealed that the defendant has a history of behaviour towards other women with whom he has been in a relationship that shows him to have behaved in a possessive, controlling and jealous way,” he said. 
Pathologist Dr Nathaniel Cary re-examined both causes of death and concluded that Ms Nicholson had suffocated after having her head forced into the bed. He also told the court that Ms Devlin’s death was caused by a blow to the back of her head.
 
Trigg denies the manslaughter and murder.
