Child-murderer Christina Robinson tells her lover her son will get his “ass kicked” in a disturbing voice note sent days before he died.

The 30-year-old killer of Dwelaniyah, 3, sent the message to her lover Chisom Innocent Onoja on WhatsApp eight days before the toddler collapsed, never to recover.

She’d met Innocent on the OK Cupid dating site, and he had visited the family home on Bracken Court in Ushaw Moor, County Durham after her husband joined the RAF.

Mr Onoja said he was unaware husband Gabriel was away in the forces.

The 16-second clip was sent on October 28, 2022, after Robinson complained to her lover about her “damn kids and the terrible night of sleep” they’d given her.

She’d sent him a video of tablets spilt on the floor and said she “felt like slapping someone”.

She said Dwelaniyah got up in the night, went downstairs, spilled the tablets and had swallowed at least one, but vomited it back up.

Twenty-seven-year-old Mr Onoja had replied expressing concern for the little boy but in the voice note Robinson replied: “Boy! He’s fine cos (sic) obviously he’s vomited it out so he’s alright.

“If he didn’t vomit it out then I would be worried.

“So now he’s picking up everything, and then he’s gonna get his ass kicked.”

Mr Onoja asked her to be “gentle” with the child, but she replied: “He will get exactly what he deserves, no more, no less.”

Prosecutors claimed she could never have taken him to hospital that day as doctors would have seen the extent of burns she inflicted on him the previous week.

Mr Onoja visited the home for the last time just days before Dwelaniyah’s death and said he “was squinting and grunting a little when he walked” and was wearing blood-stained bandages on his legs and was in pain from burns Robinson inflicted.
