Video Rant, Then Deadly Rampage in California Town
ISLA VISTA, Calif. — A college student who posted videos that documented his rage against women for rejecting him killed six people and wounded 13 others during a spasm of terror on Friday night, the police said. He stabbed three men to death in his apartment and shot the others as he methodically opened fire on bystanders on the crowded streets of this small town.
The gunman, identified by the police as Elliot O. Rodger, 22, was found dead with a bullet wound to his head after his black BMW crashed into a parked car following two shootouts with sheriff’s deputies near the University of California, Santa Barbara. The police said he had apparently taken his own life. Three semiautomatic handguns, along with 41 loaded 10-round magazines — all bought legally at local gun stores — were found in his car.
methodの副詞 methodicallyですが、「系統的に、組織的に」という意味が与えられますが、ここでは「手際よく」という訳(おぞましいのですが…)が適当かなと思いました。(Ume)
