Killer, 77, guilty of abusing girl from 1963 to 1973
A 77-year-old man from east London who killed three of his children in 1974 has been found guilty of sexually abusing a girl between 1963 and 1973.
Edward Campbell, from Enfield, was found guilty of eight charges including rape and other serious sexual offences at Snaresbrook Crown Court.
The abuse occurred when the victim was aged between four and 14, a Crown Prosecution Service spokeswoman said.
It ended after Campbell strangled three of his own children, she added.
Crown Prosecution Service (CPS) lawyer and rape specialist Kay Scudder said: "The CPS would like to thank the brave victim of rape and child abuse who supported our case to seek justice almost 50 years after her terrible ordeal began.
"No-one looking at the facts of this case would fail to be horrified by the nature of this abuse."
The defendant had pleaded guilty to manslaughter and grievous bodily harm after a psychiatric report ruled he had been depressed at the time of the killings.
Campbell will be sentenced at a later date.
