The only one to pass away in February 2019 is Kelly Mason, on 2/15/2019.
She passed away in her sleep from cardiac arrest. She had been doing pretty good with the program, but her health was just too far gone.
I'm not 100% sure, but I think she (Kelly) was the one that wasn't able to get out of the cab when she met Dr. Now at the hospital. It was a very sad episode; she was really trying hard and I think she was either back in college or trying to get back.
