A convicted baby killer was caught on camera faking shock after learning he was under arrest for the attempted murder (and later murder) of his girlfriend’s 12 week old son, Teddie Mitchell.

During a two-part special of “24 Hours in Police Custody”, a British docusery that takes viewers behind the scenes of investigations, police footage taken in 2019 showed the moment the killer of convicted babies Kane Mitchell learned he was going to jail.

“He’s completely devoid of any remorse or empathy, that’s the thing that I find really difficult. It’s all about Kane and not what Teddie went through, ”Detective Inspector Lucy Thompson said, according to The Mirror.

Police arrested Mitchell at Hinchingbrooke Hospital in Huntingdon, where 12-week-old Teddie died of his injuries. Mitchell sat next to his girlfriend, Lucci Smith, 30, in the hospital as doctors unsuccessfully tried to save the baby’s life.

The couple had been dating for about eight months when the incident occurred.

“I don’t think so. Oh my god, I would never hurt a baby. I’m not leaving my son,” Mitchell said, as Smith defended him.

As CrimeOnline previously reported, Mitchell babysat Teddie while Smith attended school in early November 2019. The couple were living together in an apartment in St Neots, Cambridgeshire, England.

During a four-week trial at Cambridge Crown Court in 2020, prosecutors detailed how the baby suffered trauma to the head because Mitchell hit him against a hard surface. Mitchell is also accused of shaking the baby and hugging it too much.

After Smith returned home from school on the day in question, she noticed that her son seemed unusually lethargic and refused to take his bottle. She contacted the baby’s pediatrician, who advised her to call 999, but Smith apparently waited about 30 minutes before calling.

Teddy was eventually taken to hospital, where doctors said the baby had a severe brain hemorrhage and a broken skull.

The BBC reports that the infant also suffered a fractured collarbone and ribs, which “would have caused Teddie to scream in pain … to a point where he became unconscious,” jurors heard.

Doctors later said Teddy would probably never get over it. After several weeks of resuscitation, he died on November 11, 2019. An autopsy report indicated that the fractured skull and lack of oxygen caused the infant’s death.

During the trial, the jury heard from neighbors that the couple had argued non-stop after Mitchell moved in. However, during an interview with the police, Smith claimed that she had a benevolent relationship with Mitchell and hardly ever had an argument with him.

Social workers said Mitchell had hit Smith before, which led to the posting of a social worker in September 2019. Mitchell told police he believed the baby was his, although one DNA test performed after Teddy’s death showed Mitchell was not the biological father.

He also claimed he had no idea how the baby developed the injuries and couldn’t explain it, despite being the only caregiver while Teddy was injured. Smith also said she couldn’t explain the injuries.

It took two days for the jury to return a guilty verdict. Mitchell was convicted of murder while Smith was convicted of child neglect for “failing to act once it was evident that Teddie was very seriously ill”.
