Old Crimewatch UK cases - any information?

[unsolved88]

I recently discovered some old episodes of Crimewatch UK on a certain site, the British program that inspired our own America's Most Wanted. I've seen some of the newer episodes, but I prefer the older reconstructions (re-enactments) to the current ones. However, some of these old episodes mention cases that I've not been able to find information about online. As such, I'm curious to know if they were ever solved. If any UK members here know more about these cases, it'd be greatly appreciated. I'm posting these cases in chronological order according to the episodes on which they were mentioned.

December 18, 1986: The murder of Lorna Hayles
(I was only able to find this entry on a UK database about Lorna's murder which states that it was never solved: http://www.unsolved-murders.co.uk/mu...nt.php?key=772)

March 17, 1988:
* The murder of Kathy Walsh in London(featured on the February 1988 episode)
* The murder of John Lawrence in Middlesex

December 8, 1988: The murder of James Gibson in Merseyside on November 15, 1988

December 6, 1990: The murder of Paul Stevens in Southall (featured on the November 1990 episode)

January 20, 1994:
* The 1986 disappearance of John Dobson
* The 1990 disappearance of Stephanie Whittaker

April 1995: Unidentified woman found in Humberside.

June 1995: The murder of an elderly woman named Christina Gray (presumably featured on the May 1995 edition)

Someone on the forbidden site had this to say about the James Gibson murder.

Well James Gibson was in fact one of the robbers behind the Preston armed robbery featured on the previous crimewatch episode. Gibson and Leonard Newsham were caught, however Gibson himself was murdered before the trial. Newsham was given 13 years.
