Brazilian doctor allegedly killed patients to free up beds

CNN has story of how authorities have arrested Virginia Helena Soares de Souza for allegedly killing 7 patients to free up space in the ICU.  Investigators are trying to discern if there were more than 7 victims.

Prosecutors allege de Souza pulled the plug on victims against the wishes of patients and their families, and in so doing broke the law. She did that to free up beds in the ICU and clear up the "clutter" the patients were causing, according to police.

De Souza was arrested in February, but was later released until trial. Her court appearance Wednesday is part of mandated monthly appearances to avoid going back to jail.

Investigators say between 2006 and 2013, de Souza ordered medical professionals working under her at an intensive care unit to alter medication and oxygen levels.
