Baby Luna had been left in the arms of Deane while her mum went to get some sleep on July 10th. Deane, from Wakefield, West Yorks, lost his temper during the night and subjected Luna to an attack when she continued to cry.

In a vicious attack he punched Luna in the face, squeezed her body and arms and shook her. Luna was taken to Leeds General Infirmary where she died in intensive care on July 14.

Police said Liam Deane, 22, was found dead in his cell at HMP Leeds on Sunday, just one month after he was jailed for viciously killing his daughter Luna in the family home.

Another inmate, John Westland, 28, appeared at Leeds Magistrates’ Court this morning charged with his murder.

Westland was flanked by two police officers and a member of court escort staff as he was brought into the dock.

He remained handcuffed throughout the brief hearing, speaking only to confirm his personal details.

Westland was told that his case was being sent to Leeds Crown Court due to the serious nature of the offence.

Do you think what the other inmate did was justifiable? A lot of people are saying he got what he deserved and others say it wasn't his place to take his life.
