Yeah, that was from back when he was with the Mets.
They had a child care area at Shea where players and other employees could bring their kids and have them looked after. Well at some point someone notices that one of Carl's kids has marks on him (I think it was a him) or other suspicious signs and, not wanting to foreshadow Penn State, reports the case to some higher ups.
Well, needless to say, the whole thing got pretty ugly, partly due to the whole aforementioned bat-shit crazy thing but also because it was one of the other wives (Mrs. Bernard Gilkey IIRC) who first noticed and pointed out the problem. I forget how it all wound up but there was definitely talk about how Carl was essentially taking the rap for his wife, an issue which was complicated by the fact that the kid, the oldest of Carl's several children, was from, how they say, a "previous relationship" and so, biologically and possibly legally as well, was his but not hers.
