I do remember the case-Neilson,I think,was from Thornbury,Bradford,which was also the domicile of the Ripper[rather more upmarket Heaton]
The Whittle family ran a prosperous coach business in Highley,which is probably why he kidnapped the daughter,hoping for a ransome.
By a weird coincidence,I was two streets away in Sheffield,the day before the Ripper,was arrested there.
A rather serious vein to RTR.
