An eight-month-pregnant teenager was killed and had her baby cut from her womb by a jealous woman who wanted her child after suffering a miscarriage.

The sadistic killer lured student Gabrielle Barcelos Silva to her house in Uberlandia, Brazil on the pretence of gifting her baby clothes.

She laced her coffee with drugs, suffocated her and sliced her open with a stiletto knife to remove her child.

Gabrielle Barcelos Silva (left before her pregnancy) was killed for her baby. Right: Just a day before her brutal murder, Gabrielle, 18, posted a selfie of her growing baby bump captioned: 'I am the happiest woman in the world.'

The 38-year-old killer then dialled 999 claiming she had given birth in the street.

When she got to hospital, suspicious doctors called police and the woman later confessed to her grisly crime.

The killer's 14-year-old son found Gabrielle's body wrapped in a blanket at their rundown house.

Today it emerged the killer hatched her horrific plan to take Gabrielle's baby after her 34-year-old partner, who has also been arrested, threatened to leave her when she miscarried earlier this year.

She is said to have targeted Gabrielle, who lived in the same neighbourhood as her, after realising she was pregnant when she spotted her in the street.

Local reports said she confessed to police she had done an Internet search for information on how to perform a Caesarian section before completing her awful act by slipping a tranquillizer in juice and coffee she served Gabrielle and cutting her open with a stiletto knife once she had killed her.

Medics at the Hospital de Clinicas in Uberlandia called police after admitting the child to an emergency neo-natal unit and confirming through tests the fake mother could not have given birth to the baby girl.

She told cops her partner knew about her plan and helped her get rid of the body. He is protesting his innocence.

The baby was today said to be stable and undergoing 'special care' after being forcibly removed from her mum's womb.

In her last Facebook post just before the sickening crime, Gabrielle, an agricultural engineering student who described herself as single, posted a picture of her heavily-pregnant tummy with her shirt lifted up, alongside the message: 'Things happen in life without people planning them and end up becoming the most important things in our lives.

'A few months ago I received a blessing from God with the news I was pregnant. I was worried at first but then I started getting used to it and today I am the happiest woman in the world because I'm carrying my unborn daughter and there's not long to go before I'm able to see her face and hold her.'

In a previous post last month, she posted a selfie with the words: 'Every day that passes I see you moving more and more and getting bigger as you grow inside your mummy.'

'I'm in love with you even before I get to know your face.'

The horrific crime prompted an outpouring of anger on social media.

Mylena Araujo wrote on Gabrielle's Facebook: 'Very sad. I hope justice is done.'

Lu Lacerda added: 'Justice should be done to punish this sickening crime.

'They should hand the killer and her partner over to the people so they can deal with them.

Lipe Wolf said: 'One day her daughter is going to read about this and see how much her mum loved her. I am speechless.'
