A student killed the newborn baby she had carried in secret by putting her in a Kellogg’s cereal box and hiding it in a suitcase, jurors heard today. ‘Cool and calculating’ Jia Xin Teo, 22, ‘probably knew’ she was pregnant when she arrived at Coventry University, a jury heard, but hadn’t told anybody she was expecting – including the father of the baby back home in Malaysia.A court heard the pregnancy was only discovered after friends in her halls of residence forced entry to her bedroom after becoming concerned about Teo and found ‘blood everywhere’.Prosecutor David Mason KC told jurors Teo had given birth on March 4 this year to a ‘full term’ baby girl, adding: ‘Nobody else even knew she was pregnant.’She then took the decision to kill her newborn daughter by placing her into a cereal box which went into plastic bag which was sealed and then into a suitcase.’ Warwick Crown Court heard Jia Xin Teo eventually admitted giving birth and told police where she had hidden the infantThe barrister added: ‘According to the account she gave the police, her baby definitely survived a least a number of minutes and was still moving when she put the little girl into the box and then the bag.’The court heard the baby’s body was only discovered two days later when Teo, by then in hospital, admitted what she had done.Mr Mason said the Crown’s case was that Teo ‘knew what she was doing’, adding: ‘She knew that her baby could have survived and yet chose to deliberately kill her’.But the prosecutor said the jury would have to decide whether the defendant was indeed guilty of murder as the prosecution suggest, or ‘whether the balance of her mind was or might have been so disturbed at the time’ that she is not guilty of murder but instead guilty of infanticide.Mr Mason said that when Teo’s friends entered her bedroom they found blood stains, smears and clots all over the room. Teo had locked herself in the bathroom but was eventually persuaded to come out.Paramedics were called but Teo refused to go to hospital and was instead transferred to a room so the blood stains could be cleaned.Mr Mason said one of her friends had helped to move her belongings, which ‘unbeknown to him’ included the red suitcase containing the baby girl.Teo eventually agreed to go to hospital and was admitted to an emergency gynaecology unit, where a pregnancy test proved positive.But the defendant refused a vaginal examination and denied giving birth. Medics knew otherwise and called police, the jury heard. Officers were sent to both the ward and her halls of residence in Coventry.Warwick Crown Court heard Teo eventually admitted giving birth and told police where she had hidden the infant. ‘The baby was removed to the mortuary at the hospital where her mother was being treated’, Mr Mason said.The following day, March 7, a bereavement midwife was sent to the hospital ‘to speak to and counsel’ Teo.The student told her she had miscarried and given birth, having been aware she was pregnant. She admitted her boyfriend in Malaysia was the father but admitted nobody knew she was pregnant, saying she couldn’t tell her parents because she didn’t know what their reaction would be, due to her age. Teo admitted her baby had been ‘alive – crying and moving’ and said there had been a lot of blood and she was scared.Mr Mason said Teo didn’t ‘show any grief, only fear of her parents and of being arrested and what would happen next’, and never asked the midwife about the baby.A post mortem examination was carried out by two pathologists but due to the short time the baby was alive, they could not establish a definitive cause of death, describing it as unexplained.Prior to being interviewed by police, Teo was seen by a mental health nurse, who asked if she had heard voices. Teo’s denial would prove ‘extremely important’, Mr Mason said, as she went on to claim in her interview that she had heard voices – some telling her to put the baby in a cereal box and others saying not to.The prosecutor told the court Teo told officers she ‘did the wrong thing’, by putting the infant in the cereal box after she gave birth on the bathroom floor. ‘She said she couldn’t control herself’, Mr Mason added.Teo said that she had put the crying infant in her sink and turned the water on in a bid to quieten her down so nobody would hear her.She told officers the baby was submerged for two or three minutes before she transferred her to the cereal box, still moving, and then wrapped the box in a plastic bag because it’s base had quickly gone soggy.Mr Mason told jurors that for a defence of infanticide, those representing Teo would have to establish that her mind was or might have been disturbed or not fully recovered from the effect of giving birth. Two psychiatrists were of the opinion that such a defence was open to her, he added.But Mr Mason said Teo had ‘deliberately hid her pregnancy from everyone’, lied to the doctors about giving birth and refused a vaginal exam.He told jurors: ‘You can infer that if it hadn’t been for the heavy blood loss the birth would have remained secret’ and said her disposal of the baby ‘required significant thought’.Teo, of Coventry, denies murder.The trial continues.
