A Texas jury sentenced a man to life in prison for murdering his then-girlfriend’s infant baby by dunking his head in the toilet multiple times to stop him from crying.

Antoine Gorman, 28, of Freeport, was found guilty of murder in March for the November 2016 death of 7-week-old Malachi Nelson.

Tashiay Nelson, Malachi’s mother, had left Gorman at her apartment to babysit the baby and her other children, who were 3 and 4 at the time, while she went to work, reported ABC 13.

At some point while Gorman was watching the children, he grabbed Malachi by the foot, held him upside down, and dunked his head two or three times underwater in a toilet, according to court documents.

When Nelson returned home from work that night, she found the children left alone and an unresponsive Malachi, Freeport Police Capt. Ray Garivey told Click2Houston.

“His face was cold, so I went to my sister’s house and I was trying to wake him up and he wouldn’t wake up,” Nelson told Click2Houston.

Nelson’s neighbors tried to help her revive the infant, but it was too late. Malachi was taken to a local hospital where he was pronounced dead.

After a police conducted search, Gorman was arrested two days later in Houston.

During Gorman’s hearing on last week, Nelson told ABC13 that her ex’s life sentence was too lenient.

“I hate him and I hope he rots in hell,” Nelson told the station.

"He dunked him like two or three times," Nelson added.

Nelson said that during Gorman’s trial, he showed no signs of remorse.

"He was shooting the finger at us the whole time. Looking back at us, laughing, playing with his hair the whole time. Being disrespectful. He wasn't showing no remorse or nothing," she told ABC 13.

Gorman will not become eligible for parole for at least 30 years.
