It is being reported that convicted child killer Robert Black has died in prison.

In 1990, he was arrested after police found an abducted 6-year-old girl in the back of his van.

He was found guilty and sentenced to life in prison for the murder of three young girls in Leeds and Scotland, whose cases had remained unsolved since the '80s.

In 2011, he was convicted to an additional 25 years in prison after being found guilty for the murder of a fourth girl, whose body was discovered in 1981.

Black was also the lead suspect in the disappearance of a 13-year-old in Devon in 1978, with no trace of the girl ever having been discovered.

The 68-year-old was in a high-security jail in County Antrim and currently the death his death is not being treated as suspicious.
