Why do many of the media reports about Sandy Hook not include the mother in their count?

While by no means universal, since the shooting at Sandy Hook Elem. happened you will see most articles stating things like ”...20 children and 6 adults” or ”...26 victims…”. What about the mother? Is she not also a victim of this act? Is she purposely left out of the body count because she is somehow complicit in the minds of most people?
Just wondering if anyone else noticed this and what your thoughts were.
