Time of Death: Dr. Rebecca Kelleher pronounced death at 6:28 p.m. on December 22, 2013, at Baptist Memorial Hospital following unsuccessful resuscitation efforts.

Immediate Cause of Death: Massive internal bleeding resulting in catastrophic multiple organ failures.

Manner of Death: Pending investigation

Notes: Medical records indicate the subject's warfarin treatment regimen had been terminated at the subject's request due to "intolerable side effects" five (5) months prior to death. The positive finding of warfarin at autopsy makes the death suspicious, and therefore, it requires further investigation.

  • Just as I thought and, massive internal bleeding resulting in catastrophic multiple organ failures and warfarin found in her system.
    Until I read both Diane's doctor and pharmacist's statements there was no real evidence of foul play or anybody to point the finger at.
    But after reading both of those interviews one person started to stand out.
    If we were given a poll I would click the name of Landon Talley.
    Two of the clues were in his BIO.
    The first one, was that he had lived in Atlanta, and the man who picked up the warfarin tablets in July was wearing an Atlanta Braves baseball cap.
    At the very bottom of his bio Landon say's that Diane had began to remind him of his wife Genevieve both of whom were shrill and confining and he needed to get rid of one of them from his life permanently.
    In his interview he didn't want his wife to find out about his affair with Diane. So it was obvious that he was prepared to stay with his wife, but Diane was the one who had to go. Diane was good at threatening so I don't doubt that Diane had threatened Landon.
    The second hint, was the man who did pick up the prescription of the warfarin wearing the old style Atlanta Braves baseball cap, fitted the description of Landon.
    The request for the prescription was made over the phone.
    Diane had refused to take the warfarin and, her doctor told her to take the aspirin.
    And Diane's cause of death is exactly what warfarin can do if not taken properly.

  • yes i doubted it its not a foul play ....

  • Hello Poppy,
    Diane told her doctor that she did not want to take the warfarin anymore, because one of the side affects was, it made her mouth sore. So he prescribed her 300mg of the aspirin instead.
    And when he last saw Diane on November the 8th she said, "Boy! I'm glad I'm off that warfarin stuff. I'd hate to give up kissing.!" Then gave the doc a wink.
    So I believe that Diane has been given the warfarin in smaller amounts, so as not to make her mouth sore again, so she was not aware of being given the warfarin. But these smaller amounts and her quite heavy drinking were a deadly cocktail.

  • yeah and it was also her fault .. now she's dead no more kissing ever

  • I think it's intresting to note that the coreners reports states:

    This confirmed that some warfarin was still within her system, although someone has already noted she was now taking aspirin, due to the side effects of warfarin..

    After doing some light research on the internet, I've notice that taking aspirin as well as warfarin can lead to bleeding. One question that should be asked is 'If ms.coates was prescribed aspirin why did she ask Moss, for some? You would have thought that if you suffered from a serious illness or had common pains, you'd carry some with you?'

    In addition we already no from Ms. Coates was under stress and suffered from alcoholism. It's very unlikely that alcohol did not have some role in here death. Although not certain yet (Newcomer to Crimescene.com) the mixture of both Aspirin, Warfirin and alcohol might be the sole reason for unfortunate death? I believe that the high levels of internal bleeding would be impossible to take effect within a few hours. I believe this mixture could have been over a long period of time or the result of foul play possible the tampering of the drugs. I will investigate further :)
