A Brazilian teenager had a courier service deliver poisoned cupcake to her friend and classmate. She watched her pal gobble the treat she laced with arsenic and fall ill within minutes. The target was received treatment and seemingly survived, initially. The hateful friend, then went to the target’s home for a birthday sleepover and watched her in the throes of death without volunteering that that she was aware of the cause.
The tragedy occurred in the city of Itapecerica, about 310 miles north of São Paulo on Saturday night.
The 17-year-old suspect, whose named has not been released, confessed to Brazilian authorities that she targeted her classmate Ana Neves out of ‘jealousy’ in an attempt to ‘scare’ her. They pair were classmates at João Baptista de Oliveira State School in Itapecerica da Serra, in Greater São Paulo.
Within an hour of eating the cupcake on Saturday, Ana Neves, who had just turned 17 the previous week, was sick and fell to the bathroom floor. The ‘poisoner friend’ watched silently as the victim was rushed to hospital, according to her father Silvio das Neves.

She fell sick around an hour after eating the cake at 6pm on Saturday but was initially discharged from hospital that night. Neves returned home for a sleepover with the suspect, unaware her friend was responsible for her illness.
Her condition took a turn for the worse on Sunday when she became ill and fell in her bathroom suffering a cardiac arrest. She was pronounced dead at the hospital, where doctors failed to revive her.
‘This girl went to sleep at my house and was there for the whole thing,’ said Ana’s dad Silvio das Neves after his daughter’s burial service on Tuesday.
‘She saw [Ana] feeling sick, she saw when I took her to the hospital and, the next day, she also saw my daughter falling in the bathroom and she didn’t show any reaction.’

Victim: Ana Neves died Sunday, a day after she ate a poisoned cupcake delivered by courier. It was the week of her birthday. The treat was sent by a classmates – pretending it was from a romantic admirer. She was buried Tuesday, same day the suspect, also 17, confessed

São Paulo Civil Police investigators analyzed surveillance cameras near Ana Neves’ home and were able to identify the license plate number of the motorcycle courier who delivered the poisoned cupcake.
The deliveryman was able to share the address to the suspect’s home.
The suspect was accompanied by her mother to the Itapecerica Police Station, where she was grilled and denied her involvement.
The teenage poisoner who was initially evasive in her police interview, after several hours questioning admitted that she purchased the arsenic online for about $11.50, [65 Brazilian Reals], and bought the cupcake at Menina Trufa, a bakery near her home.
While at home, she added the toxic chemical on the cupcake and then requested the courier service, deliver the treat at a cost of 88 cents [5 Reals].

Ana Neves took a photo of the love note that accompanied the poisoned cupcake. It read: ‘A treat for the most beautiful girl I’ve ever seen’

Coming clean as a serial poisoner, the suspect also confessed that she earlier poisoned another classmate, 17-year-old Kamilly da Silva, on May 15, because she just wanted to frighten that victim. 
CNN Brasil quotes the suspect rationalizing her crime by claiming that she targeted Kamilly da Silva because she had not gotten over her breakup with her two previous boyfriends.
She told investigators that she ‘did not intend for any greater harm to happen’ to both of the victims and that she just wanted both girls to ‘experience bad symptoms, such as vomiting.’
da Silva was rushed to a medical facility and made a full recovery, but never filed a police report.
