Diane was visited in hospital by Robbie Fowler on Friday - a visit that was covered on this website and prompted thousands of fans to post heartfelt messages of support - but the club was today informed by husband Barry that his wife had lost her battle to regain consciousness.
"We have had so many messages of support from Reds fans and non-Reds fans from around the world," Barry told LFCtour.com. "It has been truly amazing and so uplifting. I am struggling to thank everybody personally.
"If I may, I'd like to share the message our son Adam posted on Facebook:
'At 11:40pm, on the 29th of July, 2014; my mother, Diane Margaret Inder, passed away peacefully at Tufts Medical Centre, Boston, at the age of 59.
'Doctors gave us results from her MRI scans, showing that brain damage resulted from her cardiac arrest was extensive, and any chance of recovery would be very slim. If any recovery were to happen, it would not give her a quality of life my mum would have been happy with. Hence, my father and I decided it was best that we withdraw life support.
'My dad, despite his continued denial of this, is a hero to me. His attempted resuscitation of my mum while waiting for the ambulance meant that my mum was kept alive. The fact that I got to see her and say goodbye to her - even if she hasn't been conscious for the past week - meant everything.
'My mum was a woman that was told she would never had kids. When she ended up becoming pregnant with me later in life, she gave up everything to ensure that I had the best that she could provide. If there was ever something I've been 100% sure of my entire life, it's that my mum unconditionally loved me from before I was even born. I have been so blessed to share my life with such a beautiful person for 21 years.
'This is the mum that read to me as a child, sang to me when I couldn't sleep, took care of me when I was sick, willingly did all my washing and cleaning, cooked the best food in the world, always had an ear to listen, loved me more than life itself, and never, EVER asked for anything in return. I will spend the rest of my days holding her in my heart, making sure that the love she poured out on me was not in vain, but that I make her proud and reflect her loving spirit in all that I do.
'Rest in peace, Mum. I love you. I'll always be your baby.'"
