HONG KONG — A Hong Kong judge on Tuesday sentenced a British banker to life in prison for murdering two Indonesian women at his luxury apartment in 2014, bringing to a close a gruesome case that cast a spotlight on social inequality and the excesses of the financial sector in one of Asia’s richest cities.

A nine-member jury found the banker, Rurik George Caton Jutting, guilty of double murder after deliberating for less than a day in High Court. The decision was unanimous.

“I accept this as a just and appropriate judgment,” Mr. Jutting, 31, said in a statement that his lawyer read after the verdict was announced, according to a report in The South China Morning Post. “The evil I have inflicted can never be remedied by me in words or by action.”

Murder convictions carry a mandatory life sentence in Hong Kong, a semiautonomous Chinese city that has its own legal system.
