The overwhelming majority of these mass shootings have initial (and incorrect) eyewitness reports of multiple shooters. This is why it is much better to wait for the real story. The initial story is almost always wrong. People, in the midst of a stressful situation often panic, and eyewitness reports are notoriously unreliable. It's not that people are deliberately lying, but that they are so hysterical that they often do not fully process what is going on.

Moreover, the media is pretty horrendous and often gets the initial reports wrong.
