I don't mean to assume anything, but by the looks of her, your hoggie is morbidly obese. Those fat rolls are extremely dangerous to her health. I understand that some snakes are trash compactors, but that is VERY bad for their health. Just by judging by the separation of her scales tells me that she may be too fat. I don't mean to point a finger, i have just had the same experience with a couple of my snakes. To lose an animal by over feeding them is extrememly sad. If she is eating large mice once a week, i would start her on smaller meals...if she is eating more than once a week i would back her up (even then) to once every other week. Just be careful not to put her on a diet too harsh. doing that will be just as dangerous as over feeding...
