Two of the victims were in a coma after sharing the pizza and others showed severe poisoning symptoms, such as bleeding from the throat, police said.

De Oliveira said police had a letter addressed to one of the victims -- a 16-year-old identified only as Paulo. In a description provided to police, the man who had delivered the pizza said the suspect was a plump, short woman about 18 to 20 years old.
