Miss Philicoff, the girls in the gilded teller cages. There was Mister Anderson, the guard, dozing by the door in his brown uniform. There was the others took the pistol away from Mister Anderson, the guard, and The man with the gun turned to say to the man at the door, "Keep your shirt on." That was all Miss English needed. She kicked off her shoes and ran The man by the door spread his arms out and shouted, "Hey!" The man with the gun swung violently back, cursing, and fired the gun. But he'd been moving too fast, and so had Miss English, and all he hit was the The man by the door caught Miss English in a bear hug. She promptly did her best to scratch his eyes out. Meanwhile, Mr. Anderson went scooting out the front door and running down the street toward the police station in the next block, shouting, "Help! Help! Robbery!" the gun hit Miss English on the head. She fell unconscious to the floor, and all three of them ran out of the bank to the car out front, in which sat a very nervous-looking fourth man, gunning the engine. Everyone except Miss English ran out after the bandits, to watch. drove straight down the street toward the police station. The police all the police went running down there to clap handcuffs on the robbers "Come along home," said his mother, grabbing his hand. "We don't want he cried. "What did you do to the tires?" "Not a thing, sir. That happened to them in the holdup." third time. He reported himself sick and spent the two days at home, brooding, a bottle of blended whiskey at all times in his hand. As the police reconstructed it later, Mrs. Higgins had attempted to awaken him on the third morning at seven-thirty, suggesting that he really ought to stop being so foolish, and go back to work. He then allegedly poked her in the eye, and locked her out of the bedroom. Mrs. Higgins then apparently called her sister-in-law, a Mrs. Thelma Stodbetter, who was Mr. Higgins' sister. Mrs. Stodbetter arrived at the house at nine o'clock, and spent some time tapping at the still-locked bedroom door, apparently requesting Mr. Higgins to unlock the door and "stop acting like a child." Neighbors reported to the police that they heard Mr. Higgins shout a number of times, "Go away! Can't you let a man sleep?" At about ten-fifteen, neighbors heard shots from the Higgins residence, a two-story one-family pink stucco affair in the middle of a block of similar homes. Mr. Higgins, it was learned later, had suddenly erupted from his bedroom, brandishing a .30-.30 hunting rifle and, being annoyed at the shrieks of his wife and sister, had fired seven shells at them, killing his wife on the spot and wounding his sister in the hand and shoulder. Mrs. Stodbetter, wounded and scared out of her wits, raced screaming out the front door of the house, crying for the police and shouting, position across the street from the scene of carnage and went to work with a Zoomar lens. In the meantime, Mister Higgins had barricaded himself in his house, firing at anything that moved. The two cameramen in the mobile unit worked their hearts out. One concentrated on the movements of the police and firemen and neighbors and ambulance attendants, while the other used the Zoomar lens to search for Mr. Higgins. He found him occasionally, offering the at-home audience brief glimpses of a stocky balding man in brown trousers and undershirt, stalking from window to window on the second floor of the house. The show lasted for nearly an hour. There were policemen everywhere, and firemen everywhere, and neighbors milling around down at the corner, where the police had roped the block off, and occasionally Mr. 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 had the place surrounded and could eventually starve him out anyway. Higgins used his own good lungs to shout obscenities back and challenge anyone present to hand-to-hand combat. The police fired tear gas shells at the house, but it was a windy day 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 threw the rifle away. The rifle bounced onto the porch roof, slithered down to the edge, hung for a second against the drain, and finally fell barrel first onto the lawn. Meanwhile, Higgins was running through the house, shouting like a wounded bull. He thundered down the stairs and out, hollering, to fall into the arms of the waiting police. They had trouble holding him. At first they thought he was actually trying to get away, but then one of them heard what it was he was were red and blistering, from what looked like severe burns. There was another burn on his right cheek and another one on his right shoulder. Higgins, thoroughly chastened and bewildered, was led away for burn ointment and jail. The television crew went on back to Manhattan. The neighbors went home and telephoned their friends. On-duty policemen had been called in from practically all of the precincts in Brooklyn. Among them was Detective-Sergeant William Stevenson. Stevenson frowned thoughtfully at Higgins as that unhappy individual was led away, and then strolled over to look at the rifle. He touched the stock, and it was somewhat warm but that was all. Then, yesterday, this guy Higgins out in Canarsie. He says the rifle all of a sudden got too hot to hold, and he's got the burn marks to lawyer says he put it on there. Higgins says he doesn't remember doing it. That's half the lawyer's case. He's trying to build up an insanity defense." "He put it on there himself, Stevenson," said the captain with weary "How do I know?" demanded the captain. "Kids put it on before the car know," the captain told him, "is Higgins put that name on his rifle himself. He says so." her. She was to stand chicken on the southwest corner of the street. Judy took up her position at five minutes to eleven. The streets were dark and quiet. Few people cared to walk this neighborhood after dark, particularly on Hallowe'en. Judy leaned her back against the telephone Take off." "Hey!" cried the kid in the black-and-yellow costume. "Hey, they're fighting down there!" A sudden siren and a distant flashing red light solved her problems. "Cheez," said one of the kids. "The cops!" "Fuzz!" screamed Judy. She turned and raced down the block toward the schoolyard, shouting, "Fuzz! Fuzz! Clear out, it's the fuzz!" But then she stopped, wide-eyed, when she saw what was going on in the warning. They didn't even hear the police sirens. And all at once both the yellow-and-black costume go scooting away down the street. And she had the craziest idea that it was all his fault. Captain Hanks was still in his realistic cycle this morning, and he was they could get out of the schoolyard. If the squad cars had showed up a minute later, the schoolyard wouldn't have had anything in it
