It is almost impossible to know what went wrong. If the snake just regurged on his last feeding and you just moved into the place I would say it was something eviromental, as just a wild guess. The place getting bug sprayed before you moved in, the chemical they used to clean the carpets, Boric Acid placed in the A/C-Heat Ducts to keep the bugs down or any one of a hundred different problems. It is now your job to try and find out what could have gone wrong before you bring in another reptile. It of course could have been just a health issue with the snake, but the eviromental end of it is something that you can control and look at, Do you use cedar wood chips, recently used bleach to clean the cage, spray the dog for fleas or the kids for lice? Any of these checmicals can cause problems with the aniaml if they are exposed. I hope you can find the cause and if you have any questions, please let em know.
Good Luck
