"At the end of 2010 she traveled back to the East coast to resume her music career. She had spent six months taking vocal lessons to get her singing voice back, and she had written enough songs to fill two complete CD albums. That was how fast she worked once she set her mind on something.
But things didn’t work out this time. She fell in with the wrong person when she moved to New York and the man she was living with shot and killed her when they got into an argument on September 19th, 2011 in Brooklyn."
