A federal judge says marriage and the alleged embrace of a monogamous lifestyle cannot prove the innocence of a man charged in a conspiracy with his two brothers — both luxury real estate brokers — to sexually attack women. Judge Valerie E. Caproni on Monday rejected Alon Alexander's request to dismiss one count of the indictment he faces and use his 2019 engagement to be married as a defense at a trial scheduled to start next week in Manhattan. Prosecutors say all three men, who have pleaded not guilty, are accused of drugging and raping women. The judge called proof of Alon Alexander's engagement and marriage irrelevant.
