More than two hours after the 7 p.m. reports of a man possibly carrying a rifle, police spokesman Aaron Snell said Thursday night that the search was over. He said police feel confident "there is no threat to employees here at Boeing."
Snell says officers interviewed both people who called 911. He says Everett police and officers from several area departments searched.
He says the callers saw something suspicious and "did the right thing by calling 911."
A number of Boeing workers were evacuated during the search.
Boeing tweeted that both police and company security completed their search and "are confident there is no threat."
