I am so, so, so incredibly sorry for your loss. My heart breaks for you. I lost my uncle the same way last summer. My parents found him in his trailer on their property and it was a similar situation with the blood and whatnot. Our doc said it may have indeed been a rupture and his doc's knew he had a lot of issues going on. He was only 50 years old. Alcohol is a monster that tears families apart. :-(
that indeed must have been heart wrenching for you. Many things could cause this to happen, I presume there will be a postmortem and this may answer some of your questions. I would suggest that you seek some professional support to help you deal with your loss and your late wife's alcoholism, this may have left emotional scares that need healing. Have a chat with your GP.

i don't know what to say to you that must have been heart wrenching. i am sorry for your loss. alcoholism does so much damage to the body. what was the cause of death? the esophogus can rupture that would cause one to vomit blood. my prayers go out to you.
