Devon Dad killed baby in moment of ‘pure violence’, jury told

In his closing speech, Row said Atticus was difficult to feed and it could sometimes take as long as an hour.

Describing Bartlett, Mr Row said: “He would have been potentially less tolerant, less patient, less able to control his temper and frustration.

“The loss of temper and frustration may have been brief. It was almost certainly fuelled by those eight and a half pints of Stella.

“Mr Bartlett shook his infant son with force sufficient to kill him. This wasn’t an accident – it wasn’t a slip, it wasn’t rough handling.

“It was deliberate application of force to a child who could not defend himself. The fact Mr Bartlett was drunk is no excuse.”

Row told jurors the fatal attack may have been “over in seconds”.

The trial continues.
