To me, the issue isn't really that the source in question is a criminal - I think they might be a bit less reliable than the average person, but as others have noted, general people are pretty unreliable too.

But the fact that the source was also the person who has allegedly perpetrated the crimes going unmentioned and not being disclaimed to me is sloppy - even if there was additional verification done, if you are mentioning this source as the cornerstone of your article, I want to know about the vested interests that source has. Obviously, being the person that allegedly did it means you have A LOT of vested interest in how it is covered and what is revealed. If you want to talk yourself up and brag about it (which seems to be a given if you are telling a journalist about something you allegedly perpetrated) it is totally reasonable for people to be suspicious about how much is fact and how much is fiction. Humans like to exaggerate when talking themselves up.
