Trying to find TV Present about Household Annihilators : TrueCrime

I am having hassle monitoring down a collection I watched a while in the past. I believe it was British with a deal with British household annihilators. It was episodic with every episode specializing in a special household/case and there was a feminine physician all through who was explaining the psychology of why this occurs and traits/traits/pink flags to look out for in figuring out if most of these murders might be stopped. I’m fairly positive it was made within the 90s/early 2000s. I can’t for the lifetime of me discover this anyplace! Any assist to trace it down is appreciated.
