Official cause and announcement

The Los Angeles County coroner ruled that the official cause of death was community-acquired pneumonia, with iron deficiency anemia and multiple drug intoxication as contributing factors (CNN). The coroner made the announcement on February 4, 2010, after toxicology tests were completed (Reuters).

Fred Corrigan, the chief medical examiner, emphasized that the pneumonia was acute and consistent with a community-acquired infection (CNN). Acute pneumonia was confirmed by lung examination (CNN).

Community-acquired infection: The pneumonia was diagnosed as community-acquired, meaning it originated outside a hospital setting (CNN).

Anemia and external factors

Severe iron deficiency anemia left Murphy weak and vulnerable to respiratory infections (ABC7 Los Angeles). The coroner noted that the anemia may have been exacerbated by heavy menstrual bleeding (ABC7 Los Angeles).

The coroner documented severe iron deficiency anemia, with hemoglobin levels far below normal (Los Angeles Times).

No definitive external cause—such as mold or environmental toxins—was identified in the official investigation (CBS News).

Toxicology findings

The autopsy revealed hydrocodone, a prescription painkiller, at elevated levels (TheWrap). Over-the-counter cold medicines containing acetaminophen and chlorpheniramine were also detected (TheWrap). The medications detected were over-the-counter and prescription cold medications (Reuters).

No alcohol or illicit drugs—including cocaine, heroin, or methamphetamine—were found (Reuters).

Investigation

The coroner deferred the cause of death until toxicology was complete, leading to weeks of public uncertainty (Autopsyfiles.org).
