More regarding the cause of death: Necrotizing pancreatitis
Never heard of that malady, but it sound nasty.
Necrotizing pancreatitis is primarily caused by severe acute pancreatitis, which can result from factors such as gallstones, excessive alcohol consumption, trauma to the pancreas, high levels of calcium or cholesterol, and certain medications. When the inflammation is severe, it can lead to tissue death due to lack of blood flow, resulting in necrosis.
