Murray was born in the Bronx, New York, to poor, drug-addicted, HIV-infected parents. She became homeless just after she turned 15, when her mother died of AIDS, and her father moved to a homeless shelter. Murray's life turned around when she began attending the Humanities Preparatory Academy in Chelsea, Manhattan. Though she started high school later than most students, and remained without a stable home while supporting herself and her sister, Murray graduated in only two years. She was awarded a New York Times scholarship for needy students and accepted into Harvard University, matriculating in the fall semester of 2000. She left Harvard in 2003 to care for her sick father; she resumed her education at Columbia University to be closer to him. In 2006 her father died of AIDS. She eventually returned to Harvard in 2008 and graduated in June 2009 with a bachelor's degree in psychology. As of August 2009, she had begun taking graduate courses at Harvard Summer School and would like to earn a doctorate in clinical psychology to counsel people from all walks of life.
