DURHAM, N.C. — A member of an alleged Durham cult pleaded guilty Monday for her role in the 2010 deaths of a 4-year-old boy, who the group's leader thought was gay, and a woman who had been trying to get out of the religious sect. Durham County prosecutors said Smith and two other women were in thrall to Pete Moses, leader of the Black Hebrews, and lived with him in a home on Pear Tree Lane in southeast Durham. The three feared him and called him "Lord," authorities have said.
