Matthew Smith was found guilty of murdering Isobel Parker, who he left to die in the bathroom of her Essex home in July last year after finding out she was pregnant with her new partner.
The twisted 23-year-old then sent a vile text to her younger sister saying: “By the time you get there it will be too late.”
She was found lying in the bath with cable ties around her neck after Smith had strangled her in the kitchen.
Chelmsford Crown Court heard how Iosbel, 24, had ended her relationship with Smith, who she had two children with, seven months earlier.
