TEMPLE HILLS, Md. (WJLA) — A Prince George’s County mom who pulled her child out of school because she said mold in the building was making her daughter sick may be onto something.

In this age of spreadsheets and word documents it’s easy to see how someone could send the wrong attachment in an email. But in this case that wrong attachment included information the Prince George’s County School District apparently did not want public.
