Why is "Buried in Grief" still on The Huffington Post app?

I read The Huffington Post on their iOS app on my old iPhone 4. Since Dec 19, 2012, there has been one article on the main page of the USA edition (but actually listed as part of the Money section) that has not been replaced with something current. The title is "Buried in Grief", and it is about a family dealing with a dead son's student debt. Every other article is updated regularly, many daily, but this one persists.

Why?
