On Twitter, employees tweeted their own eyewitness accounts.
“We were sitting in a meeting and then we heard people running because it was rumbling the floor. First thought was earthquake,” product manager Todd Sherman tweeted. “After existing [sic] the room we still didn’t know what was going on but more people were running. Seemed serious and not like a drill. We headed towards the exit and then saw more people and someone said that there was a person with a gun.”
