Kane Kennedy, a 20-year-old dad, has been jailed for life.

The man was jailed after it was found out that he smothered his seven-month-old son to death after he inflicted ‘obscene’ injuries on him.

According to Metro UK, Kane Kennedy forcibly got hold of Oskar Jobey-Kennedy’s testicles by either gripping, pinching or twisting them.

He then pushed his fingers down the throat of the defenceless baby before finally placing his hand over Oskar’s mouth at the family home in Morecambe, Lancashire.

Kennedy gasped in shock at Preston Crown Court as he was told he must serve a minimum of 18 years in detention before he can be considered for parole.

Court heard Kennedy was a regular cannabis smoker who became ‘bad-tempered’ when he could not get hold of the drug and argued regularly with Oskar’s mother, Tia Jobey, 19.

Before Oskar’s death on October 1 last year, Jobey sent texts to Kennedy in which she confronted him about previously pushing his fingers down Oskar’s throat and putting his hand over his mouth.

Sentencing, Mr Justice Davis told the defendant: ‘Oskar was seven months old when he was killed by you. Obviously he depended on those who had charge of his care to protect him and in his case both of those with immediate responsibility failed him.

‘His mother knew that he was at serious risk and she did nothing adequate to protect him.

‘Her culpability pales into insignificance compared to you. You are the one, on the jury’s verdict, that killed that tiny baby.

‘I am quite satisfied that what you did in the early hours of October 1 2015 was not a single isolated act … you had deliberately ill-treated that child in the days and weeks prior to his death.’

Although the judge accepted that Kennedy did not intend to kill his son, he questioned whether his actions were ‘out of some perverse kind of fun’.

Last week, Kennedy, formerly of Harewood Avenue, Heysham, was convicted by a jury of murder. He had denied murder and manslaughter.

Following conviction, detectives investigating the case described the injuries inflicted on Oskar as ‘frankly obscene’.

Jobey, 19, of Morecambe, pleaded guilty at an earlier hearing to causing or allowing the death of a child and was sentenced last week to 30 months in a young offender institution.

The court heard Jobey and Kennedy started arguing two months before Oskar’s death over Kennedy’s use of cannabis.
