    Jenny entered the library seeking just the right information. The problem wasa tricky one. She watch enough of those TV crime shows to know that. She

    approached the young man behind the information desk. " I wonder, couldyou show me where I can find information on poisons?"

    "What kind of poisons?" he asked her with a nice smile. "Too many bugs onyour ros bushes?"

    "Oh no, I'm a mystery writer and I want to know an untraceable poison in one

    of my books to kill off a bad guy," she told him, using the line she'd rehearsedon front of the mirror.

    Even though Max had one foot in the grave and the other on the banana

    peel, Jenny knew his kids would blame her for his death. Unless he died ofnatural causes, they'd suspect her and demand an autopsy. After all, evenunder the terms of prenuptial agreement, she d get a life estate in the houseand its content, and a pretty substantial sum of money, too. So the poisonhad to be untraceable.

    It seems that most poisons were traceable. But. There was one that seem to

    fit the bill. She headed home after stopping at the drug store to refill Max s

    medications and pick up a few things for herself.

    She came home, changed into sweats, painted and reprinted her nails and

    finally helped Max with his medications, as usual. She slept restlessly that

    night with Max in the next room. She could hear him wheezing through the

    walls. Max was old, with cardiac problems and asthma. How long could he

    live anyway?

    Max suffered seizure and was brought to the hospital, treated and released.

    Over the next three months, Max condition deteriorated and became

    weaker, more confused and suffered headaches and dizziness. During the

    last visit from his kids, Max died. Jenny jumped for Joy and started packing

    for her Grand Cayman vacation.

    If not for the faint smell of almonds present during autopsy, the medical

    examiner might never have known there was a found play. What had Jenny

    used to kill Max?

    Cause of Death

    Immediate (primary) cause of death: it iswhen trauma or diseases kill quickly thatthere is no opportunity for sequelae orcomplications to develop.

    Proximate (secondary) cause of death:it iswhen the injury or disease was survived for a

    sufficiently prolonged interval whichpermitted to the development of serioussequelae which actually caused the death.

  • 7/26/2019 Autopsy, Causes


    Mechanism of death

    It is the physiologic derangement orbiochemical disturbance incompatible
