Because I happened to be on-line at the time,

I heard about the San Bernadino shooting pretty early and turned on the TV. As the situation unfolded, they interviewed several eyewitnesses, who all said the SAME thing. There were THREE shooters. Heard it from at LEAST three different witnesses, who had different views. Then, when they finally had a shootout with the black SUV, and two were killed, all the reports said one of them had run away, into the neighborhood, and officers started going door to door, while helicopters circled overhead.
I finally got tired of watching, but later I saw the evening news reports on the massacre. Seems two gunmen, actually one being a woman, were killed, and the authorities wee treating it like a done deal. What the heck happened to the third shooter? The witnesses were pressed, at the time, by the interviewers who said, repeatedly, 'Are you sure you saw THREE?', and they all said YES!
Just wondering what the 'official' explanation is, concerning the discrepancy...
