A blood-stained bootlace left at a murder scene could prove whether Levi Bellfield killed a mum and daughter, it has been reported.
Bellfield, who is currently serving a life sentence for killing schoolgirl Milly Dowler and two others, is said to have admitted to the murders of Lin and Megan Russell in Kent in 1996, according to a lawyer.
At the time, Michael Stone was found guilty of the murders, as well as the attempted murder of Josie Russell, but has continually protested his innocence.
