her mothers mini-van; the girls mother; The two-and-a-half-year-old girl girl was rescued

It seems that this Yahoo! Canada News article - "Lévis toddler rescued from under car" on January 11, 2010 - is suffering from a shortage of apostrophes. First it's missing from her mother's mini-van,
and then it's missing from the girl's mother. Yahoo! Canada was borrowing the news from a CBC News article that has the apostrophes correctly in place,

but features an extra girl in the photo caption. Here's a link to the CBC News article.
