Sinead Connett admitted to concealing her baby in a towel and three Marks and Spencer’s plastic bags before putting him into a drainage pit at the bottom of her parents’ garden.
The newborn baby boy was hidden away for almost three years without her family’s knowledge before a plumber made the devastating discovery.
Sentencing Connett to 12 months in prison for concealing the birth of a child, Judge Jeremy Richardson described the act as so dreadful that it almost defies description.
The discovery was made after her father called in a plumber after having problems with the drains at his home.
Judge Richardson said: I have made the decision that you will go to prison immediately. You deceived everyone in a latticed web of lies.
You are the architect of this tragedy. As a consequence of your truly deplorable conduct you have brought misery and shame on you and your family.
The child’s body is thought to have been placed in the drain at the property in Grimsby, Lincs., on August 9, 2013, but wasn’t found until almost three years later on February 11, 2016.
When initially questioned by police, Connett denied the baby was hers, but blood stains on the towel matched a voluntary DNA sample she gave to the police.
Connett then admitted the baby was hers but told officers he was the result of a rape by a taxi driver after a work night out in Hertfordshire in October 2012.
However, that lie was exposed when a series of texts to her colleagues and mother revealed she had not gone to the work night out but had instead met up with her mother in London.
She also told police she was unaware of the pregnancy until it was too late to terminate it, but police found medical records showing she had visited her GP in January 2013, who recorded she was pregnant.
Connett, recently of Hertford, Herts., eventually told officers in her final interview she gave birth to a stillborn baby boy on August 9, 2013 in the bathroom of her flat in Margate, Kent., without any medical help.
She later dumped the baby’s body in the drainage pit at the back of her parent’s home.
Connett’s father phoned for a plumber three years later after the couple began having problems with their downstairs toilet and the body was found.
