Twisted killer Christopher Halliwell targeted young women, brutally murdered them, and then buried their bodies in shallow graves.

His victims, Sian OCallaghan and Rebecca Godden, were in the prime of their lives when Halliwell murdered them.

He was handed a rare whole-life order, meaning he will never be released at Bristol Crown Court in 2016 after being convicted of Miss Godden’s murder.

If it had not been for the dogged actions of one police officer, Becky's remains may never have been found and her killer could have escaped justice for her death.

Police believe that Halliwell is a serial killer. The question is, how many?”
