What is a untraceable cause of death?

Answer 1

When a person dies but was NOT in the presence of a physician (i.e. in a hospital), the coroner must do an autopsy. If circumstances are suspicious, it would also be a forensic autopsy. In both types of autopsy, the coroner inspects the skin, underlying tissues, muscles, heart and organs, as well as the eyes and brain. in some instances, cause of death (cod) is obvious -- for example, gunshot, strangling, beating. Tissue and blood samples are taken to test for common problems that could lead to death, especially when the cause of death is not obvious. The tests performed often take days, weeks, or months to process and can reveal a variety of known drugs, drug combinations, or other toxins such as poisons.

An untraceable cause of death is typically from a drug or poison that "leaves no traces" or the drug has a short half life and its traces are gone quickly. However, forensic science makes advances every year in creating new tests to find uncommon causes of death, and to identify what may currently be "unidentifiable" or an "undetermined" cause of death. There are very, very few "weapons" that cannot be easily traced nowadays.
