Shannon was being held at the jail after he pleaded guilty to threatening to commit a crime, resisting arrest, assault and battery, and vandalism, the district attorney’s office said.

“It’s not common that people die in jail,” O’Keefe said by phone. “Unfortunately, drugs do find their way into jails in very inventive ways. It’s a very difficult problem to address.”

A person who delivers or gives a prisoner drugs can be sentenced to up to five years in state prison.
