It sounds like the article is claiming that Mrs. Alito was crying for Mary Jo, doesn't it?
No. It sounds like it was an additional factor.
Yes, that Mrs. Alito was crying for Mary Jo in addition to crying about the attacks on her husband. But why would she be crying for Mary Jo at all? Even as an additional factor? She didn't know Mary Jo personally. And from the article, it doesn't even sound as though her husband knew her really well either.
