:::The title is fine, that other minor shooting is not notable enough for its own article, two people shot or a single murder is local news, not eneyclopedic, disambiguation is only necessary when there are multiple articles. Lastly I am sure a bunch of idiots and assholes and innocents were shot and killed before on or around the Columbine massacre, Penn State massacre, or Virginia Tech massacre but that doesn't we need to edit the common name referenced titles for them as well.
