Ms Liu killed her seven-day-old son in suspicion of a revenge against her ex-boyfriend in Taiwa.
A young mum is accused of drowning her seven-day-old baby boy and dumping his body in the bushes where he was eaten by maggots.
Police found the remains in a red plastic bag hidden in the bush outside the 21-year-old mother's house at Miaoli county, west Taiwan, reported Apple Daily .
The boy's body had been feasted on by maggots, with only a foot and a few organs available for use in DNA identification tests.
Prosecutors believe Ms Liu feared that her parents would find out about the baby and wanted to take revenge on her ex-boyfriend.
The incident came to the light as police and social workers visited the mum - only known as Ms Liu - on February 23.
This was after she was found to have violated Taiwan’s Household Registration Law, which states that all children are to be registered within 60 days of birth.
In a confession to police, Ms Liu broke up with her boyfriend after realised that she was pregnant.
She had not registered her child after giving birth to a baby boy at a clinic on December 15, 2018.
She took the baby away from the clinic a few days later and took him to a temple at about 150 feet from her home.
There she allegedly drowned her son in a sink filled with water.
She then put the body in a plastic bag and discarded him in the bushes outside her home.
Authorities said she at first denied having given birth, claiming she went to the clinic for a tumour removal.
She later cracked under questioning and admitted to having drowned her newborn as she could not afford to raise a child as a single mother.
"I don't plan to keep the child, also I couldn't afford to," she told the police.
Ms Liu claimed she and her family did not have the financial means to raise the child.
It is unclear whether the woman’s parents were aware of the alleged murder.
Miaoli police have revealed that Ms Liu gave birth to another son at the age of 17, but the child was handed over to her then-boyfriend’s family to raise.
She was detained a day after the revelations and faces murder charges.
