The death of a patient in Hospital San Juan de Dios Tuesday may have been a mercy killing.
Hospital security workers detained a former nurse after a 55-year-old patient died. The Fuerza Pública said that the women who was dressed as a nurse, gave the victim some type of injection.
The two women are believed to have been neighbors in Desamparados.
Investigators identified the dead woman as Lilliam Arias Prendas. The woman in custody has the last names of Barrantes Moreno and is 63 years old, said police.
Investigators are awaiting the results of an autopsy to determine the cause of death, although they suspect that the injection at least hastened the death.
The former nurse, who is retired, made her way to the fourth floor of the hospital on the strength of an identification card, said police.
