(B) on that day, he was in a traffic accident; (C) immediately after the accident, Mr. Parra became ill, suffered a severe decline in health, and died four days later; therefore, the accident must have caused the death. While this logic might follow more seamlessly with a healthier individual, there are too many other factors at play in Mr. Parra’s case. In the absence of any physical evidence to determine the medical effects of the accident on Mr. Parra, his list of illnesses is too long to attribute causation to the accident. To support her case for benefits, it is the plaintiffs burden to establish that the accident caused her husband’s death, or at least was an external event that set in motion a series of events that resulted in his death.
