He then allegedly poked her in the eye, and locked her out of the bedroom. Stodbetter, who was Mr. Higgins' sister. Mrs. Stodbetter arrived at the bedroom door, apparently requesting Mr. Higgins to unlock the door and heard Mr. Higgins shout a number of times, "Go away!

Mrs. Stodbetter, wounded and scared out of her wits, raced screaming In the meantime, Mister Higgins had barricaded himself in his house, search for Mr. Higgins. He found him occasionally, offering the at-home Higgins would stick his rifle out a window and shoot at somebody. The police used loudspeakers to tell Higgins he might as well give up, they Higgins used his own good lungs to shout obscenities back and challenge and all the windows in the Higgins house were either open or broken. Higgins was able to throw all the shells back out of the house again. The show lasted for nearly an hour. Then it ended, suddenly and dramatically. Higgins had showed himself to the Zoomar lens again, for the purpose of shooting either the camera or its operator. All at once he yelped and Meanwhile, Higgins was running through the house, shouting like a wounded bull. He thundered down the stairs and out, hollering, to fall They had trouble holding him.

Stevenson frowned thoughtfully at Higgins as that unhappy "Just what are you trying to say, Stevenson?" he demanded. Higgins says he doesn't remember doing it. That's half the lawyer's case.

He went around trying to prove it, and getting all upset, and pretty soon they had to put him away in the nut hatch. Remember?" "Forget this silly stuff, Stevenson," the captain advised him. The day after Jerome Higgins went berserk, the afternoon mail brought a crank letter to the Daily News Unfortunately, this letter was not read by the same individual who had seen the first one, two months before. At any rate, it was filed in the same place, and forgotten. "Listen, lady," said the kid in the red mask, aggrieved, "we got a long way to go to get home." "Yeah," said another kid, in a black mask, "and we're late as it is." black knit cap jammed down tight onto his head. "Why can't we go down there?" this apparition demanded. Take off."
