Monster Georgia father is sentenced to 50 years in prison for poisoning his 18-day-old daughter's bottle of breastmilk with antifreeze to avoid paying child support

A Georgia father was sentenced to 50 years in prison after he mixed antifreeze into his 18-day-old daughter's breastmilk in order to poison her.

Curtis Jack was arrested in October 2020, after his infant daughter, named Madison, became sick.

She tested positive for ethylene glycol — a chemical found in antifreeze.

Investigators found Jack had collected bottles of breastmilk from the child's mother two weeks earlier while she was in hospital after giving birth to their child, but did not want to pay child support after accidentally getting his co-worker pregnant.

'After delivering the breastmilk to the child's grandmother, who was also caring for the woman's other daughter, the child became critically ill within 24 hours, suspected of being poisoned.

'Jack admitted to adding antifreeze to the breastmilk to South Fulton Police Department detectives,' police said in a statement on social media.

Jack later admitted to adding the chemical to his newborn daughter's milk in order to avoid paying child support.

Within 24 hours of drinking the milk, the baby girl became 'critically ill' and was suspected of being poisoned.

The mother of the newborn told police how Curtis had tried to get her to terminate the pregnancy for entirety of the gestation. 

The baby was born in September of 2020. The two had been in an 'intimate relationship' since January of that year, police said.

'During the trial, the State presented testimonies from the child's mother, grandmother, law enforcement officers, and medical experts, including a demonstration of how easy it was to poison the breastmilk,' South Fulton police said.

'It hit home because it was an 18-day-old baby,' said South Fulton Police Sergeant Pserda Dickerson to Channel 2.

'It's beyond getting a confession we still have to prove someone committed the crime. You still have to prove that the person is guilty,' said Dickerson.

The jury found Jack guilty on all counts, including attempted murder, and he was sentenced to 50 years, with 40 years to serve in custody. 

Antifreeze even if consumed in tiny quantities is extremely toxic and can result in drowsiness, vomiting, kidney damage and death.

The child's mother declined to make a statement following Jack's sentencing, but the little girl is said to be doing fine.
