I don't know anything of this specific case, but yes the Jeremy Kyle show very much follows the form of Jerry Springer. Lots of shouting and bleeped swearing. An audience that actively catcalls the participants. Not the finest broadcasting.
I've certainly read that some people actively connive to get on the show - a free trip to Manchester where it's recorded, some expenses and a stay in a hotel. Those can be incentives enough for some. As long as the producers get a show, they're not too bothered. But there might be question marks about post-show support from those who aren't play-acting for the cameras.
The show has been a staple of ITV's daytime lineup since 2005, and Kyle had a brief attempt to take the format to the US making a couple of syndicated seasons of the show from 2011-2013.
It's the TV equivalent of bear-baiting, although it seems to do solidly enough in the ratings for the show to keep running.
As I say, I know nothing about the specifics of the case, but it may be that the facts just haven't emerged yet. Murders can be reported, but prior to a court case, everything must be factual. Anything likely to prejudice a subsequent court case can't be reported:
With suicide, it's more about being considerate around the subject. Precise methods aren't described and reasons for a person taking their own life aren't hypothesised. In many instances, reporting about suicide will be accompanied by links to support organisations.
Post reality-show support has become a significant issue in the UK with the separate deaths of two previous contestants from Love Island. While there is some level of screening before the contestants are chosen for these things, and there is some support afterwards, it's not clear how much there is. Either way, these shows don't always provide much support after the show's aired.
