Sister makes emotional plea to find killer of South Yorkshire woman who was murdered in her own home with an electrical cord

Wendy Gallagher, who was 24 when she died, lived alone at her home in Princes Street, Barnsley.

She was last seen in Barnsley town centre on Friday, January 18, 1991. Her body was discovered the following Monday, January 21, after concerns were raised that nobody had seen her.

Tragically, Miss Gallagher's parents have since died without ever finding out who was responsible for the murder of their daughter

Now, 30 years on, Miss Gallagher's sister Maureen has made an emotional plea to find who killed her younger sister.

She said: "Although i's now been 30 years, the distress of losing a little sister never fades.

"The trauma of this had a devastating effect on my parents who have now both passed away never getting any justice for the murder of their youngest daughter."

Detectives will now be taking advantage of advances in scientific techniques to re-examine evidence in the case for previously undetected traces of DNA.

They also urge anyone with any information which they have previously not disclosed, to get in touch.

“Advances in science mean that we have so many more forensic opportunities now than we did in 1991. However, I also want to encourage anyone who holds any information about her death, who has not disclosed it previously, to contact us.

"Allegiances and relationships change and diminish over time and it’s never too late to tell us what you know.

“Seeking justice is as important to us now as it always has been. You may think it insignificant, but even the smallest bit of information can help us piece together what happened.”
