Reward for Thames body killers

Zoe Parker was known to work as a prostitute

Police are making a fresh appeal and offering a reward to help trace the killer of a woman whose body was discovered in the Thames nearly two years ago.

Zoe Parker went missing on 17 December, 2000, before her dismembered body was found 11 days later.

Despite several arrests during the investigation, no charges have been brought in the case.

Ms Parker disappeared from the Hounslow area of west London and had learning difficulties.

We need to bring the perpetrator of this horrific crime to justice

Detective Chief Inspector Anthony McKeown

The 24-year-old was also known to have worked as a prostitute and was last seen with two men.

Detective Chief Inspector Anthony McKeown said: "This is the third year the family will be facing the harrowing prospect of Christmas.

"We need to bring the perpetrator of this horrific crime to justice."

"We are offering a reward of £7,500 for information leading to the arrest and conviction of the person, or persons, responsible for the murder."

Zoe's aunt Pauline Knott said: "It gets harder and harder as time goes on, and we are angry that the person that did this has not been brought to justice.

"I will never be able to get what happened to her out of my head. It's sick, absolutely sick."
