Sorry, but why would anyone even bring up to media that they had been in a fight with their mother while discussing an alibi? Websleuths has ruined me when it comes to people openly stating they had just gotten in an argument with someone etc. If it's to excuse scrapes/bruises, well.. that's a rather terrible mother/son relationship, lol. I literally can't think of any other reason why that would be brought up unless he rambled for hours and the reporter chose to just report that part or something. But if I were talking to the media regarding my DNA being collected to rule me out I definitely wouldn't proudly portray myself as a work-skipping, parent-fighting, no-show.. JMO since I have no idea who this person is. But like how much easier is it to just say "Oh I stayed up late reading and overslept"???
I'm hearing the chimes of the hinky bells, and hopefully it's just because of how weird that article/interview was.
