There were quite a lot of murders and disappearances in Norwich and Ipswich in the 90s and early 00s when Wright was around. Yet once he was imprisoned they seemed to stop. Natalie Pearman (1992), Kellie Pratt (2000), Amanda Duncan (1993), Michelle Bettles (2002) to name a few. All fit his M.O. Be a bit of a coincidence if at the same time Wright lived in the area there was another serial killer living there who happened to have the same M.O, who then decided to stop once Wright got banged up. Norfolk police have always shown little to no interest in the cases though. Same with mainstream media for some reason. Didn't Wrights dad live in Trimley? Wright was definitely familiar with the area at least.
The issue is that once someone like Wright is caught, sentenced and imprisoned, there then becomes very little momentum to then pursue any further possible murders.
The thought process being that the perp has been caught, so let's move on.
A completely wrong way to think, because all it does is deny the families of other unsolved murders; that have almost certainly been committed by the same man, a chance to have justice.
The CPS are hardly interested once a guilty sentence has been confirmed and the culprit imprisoned.
That's why justice is more about obtaining a guilty conviction for at least something, than it is to do with knowing the whole truth and finding closure for all those other victims who have slipped through the net.
There are likely scores of "unsolved cold cases" whereby the real culprit is almost certainly known, but which have never been officially connected to a perp who's already serving time for other murder/murders. The police simply don't have the resources, or mandate to keep looking and investigating once a perp has already been convicted.
The Yorkshire ripper was a prime example of that. There are certainly more victims that should have been officially linked to him, but once they got him imprisoned, nobody in authority really seemed to be driven enough to seek justice for all those other forgotten victims.
It's sad, but that's how the justice system works.
