The child’s body was allegedly disposed of shortly after her birth on Feb 26, with the placenta and umbilical cord still intact. It was found wrapped in a garbage bag by an employee from a recycling company, who had been sorting through the trash.
A 24-year-old woman and her 23-year-old boyfriend from Singapore were identified as key suspects by Taiwanese police.
The couple reportedly flew into Taiwan on Feb 19 and returned to Singapore on the afternoon of Feb 26.
Taiwanese authorities have been trying to determine whether the baby had been dead or alive at birth.
A forensic doctor conducted a test by placing the lungs and other organs in a basin of water. The doctor found that the lungs floated to the top, which he said indicated the baby had been able to breathe on its own after it was born, according to the Liberty Times.
The lung float test, however, is seen as unreliable by some forensic pathologists, as other factors may cause the organ to float in water.
According to Taiwanese law, a mother who kills her newborn may be jailed for at least six months or up to five years.
If the father had killed the newborn, he could be given the death penalty or life imprisonment, or jailed for at least 10 years, reported Liberty Times.
The forensic researchers are still investigating the cause of the baby’s death, and their report has not been released, said Taiwanese newspaper China Times.
The Taiwanese authorities may approach Singapore for help with the investigations upon receiving the report, the newspaper said.
