Regular cannabis smoker Kane Kennedy will be sentenced later for the murder of his seven-month-old son in October last year.

Kennedy, 20, was said to have been "bad-tempered" when he could not get hold of the drug, which may have led to the abuse he carried out against Oskar Jobey-Kennedy.

Preston Crown Court heard a catalogue of non-accidental injuries were identified in Oskar's post-mortem examination, with a total of 13 marks to his face and neck.

There was also bruising to both testicles, with a jury being told such injuries would have caused "immense pain" when Oskar was alive.

Kennedy is believed to have forcibly got hold of Oskar's testicles by either gripping, pinching or twisting them.

He also pushed his fingers down Oskar's throat and then placed his hand over the mouth of the child who was smothered to death at the family home in Morecambe, Lancashire.

Kennedy, formerly of Harewood Avenue, Heysham, denied murder and tried to blame Oskar's mother, Tia Jobey, but was unanimously convicted.

Jobey, 19, pleaded guilty at an earlier hearing to causing or allowing the death of a child.

Last week she was sentenced to 30 months in a young offender institution.
