Toxicologist links sedative to boarding house murders.
- Victims of a series of murders were identified through medical records provided by social security, but the cause of death remained unknown, hindering murder investigations. Police sought the expertise of toxicologist William Phillips in November 1988 to analyze tissue samples from the victims using a radioamino acid test, revealing the presence of the sedative fluorazepam, linking it to Dorothea Puente's boarding house where the drug was found.
- Phillips further utilized a tandem mass spectrometer to detect the drug's concentration in the samples, although varying levels due to bodies being underground for different periods made it challenging to determine if the drug caused the deaths. Despite this, all samples were linked to Puente, providing enough evidence for police to charge her with the murder of her tenants, revealing her method of charming residents, drugging them, and burying their bodies in her backyard. Puente was convicted of multiple murder charges in 1993, receiving a life sentence without parole.
