From Jade & Casey (Kelly's sisters):

Kelly passed away peacefully late last night surrounded by her family. She fought her cancer hard right up until the end, but now she can rest. Her family is so grateful for everyone who reached out with love, support and prayers, and everyone who provided meals or made donations to help support Kelly's family through this last year of her life. The outpouring of love is such a testament to the many lives Kelly touched and the many people who loved her. 

A celebration of life will be held in January and information will be posted here.
