A 15-year-old girl told a jury yesterday that Hector Ayala, 59, a man she once considered family, tricked her into having sex by saying that it would ward off misfortune and help make wishes come true. The girl is the third to testify at trial that Ayala, who is charged with rape, aggravated sexual assault and several related offenses having to do with being a crafty son of a bitch, fooled her into sex by invoking untold mysticism. She said that when she was 13, Ayala read her Tarot cards and said that he saw bad luck in her near future. He told her that it could be averted if she allowed him to perform oral sex on her. "He was reading my cards and told me that I wasn't on a good path and that I had to do these things called 'five' and 'seven' to make things better," the girl said.
