You should contact a medical malpractice/ personal injury attorney as soon as possible. Even if you do not have a claim, it could at least put you at ease.

I agree with Mr. Solomon's recommendation. An attorney experienced in handling medical malpractice cases can help identify the facts most relevant to whether your mother was the victim of negligent medical care. There are often mistakes made during the course of medical care which, though inexcusable, do not harm the patient. We are happy to discuss this matter in more detail and hopefully find out exactly what went wrong and if your mother's death was avoidable.
