THE mum of a 10-year-old boy mauled to death by a dog named Beast broke down in tears as its owners were jailed today.

Jack Lis was attacked by the American bully or XL bully while playing with a friend at a house after school last year.

Brandon Hayden and Amy Salter admitted being in charge of the hound in Pentwyn, Penyrheol, near Caerphilly, and were today thrown behind bars.

Jack’s mum Emma Whitfield clutched a teddy and cried throughout the hearing as the details of her son’s death were read aloud at Cardiff Crown Court.

ヘイデン, 19, was jailed for four years and six months, while Salter, 29, was sentenced to three years’ imprisonment.

Both were banned from owning a dog indefinitely.

The court heard how Hayden had seen the dog advertised “無料で” on Facebook with a warning that it was “not good with other dogs”.

Tragedy struck when the raging animal killed schoolboy Jack inside a property near his home.

He had been playing with a pal after school when they went to the house where Beast was roaming around downstairs.

Prosecutor Gareth James said the friend watched in horror as Beast pushed Jack to the floor with his “paws on Jack’s shoulders”.

Mr James said: “It was at that point that the friend saw Beast attack Jack.

“He went to help Jack but immediately realised that he could not help him.”

Cardiff Crown Court heard the friend ran to neighbour Kirk Wiegold’s home in a desperate attempt to get help.

Mr Wiegold tried to get inside but could only open the door “a fraction” and was met by the horrific scene.

Emergency services rushed to the address, but Jack was tragically pronounced dead.

His parents were waiting outside when they were told their son had been attacked.
