Justice for Nikki Allan
Twenty years ago Nikki Allan, a seven-year-old girl, was murdered on Wear Garth estate in Sunderland. It was a crime of extreme brutality. Nikki’s body was found in a derelict building – she had been battered over the head and stabbed 37 times.
No-one has ever been convicted of the evil murder of Nikki although the alleged murdererGeorge Heron admitted the offence . 20 yrs on and the family still seek justice
The self confessed but alleged killer George Heron, then 24, lived on the same estate, having moved in only weeks earlier with his sister. At first Heron denied knowing Nikki, but he admitted he did after witnesses came forward to say they had seen him with her on several occasions.
