Joshua’s parents are now calling for extra time to be added to the killer’s sentence.
At the time of sentencing, the judge imposed a 14-year term. The Halls say the latest developments demonstrates that was too lenient.
“We want time added on to the sentence of Josh’s murderer. It was lenient in the first place,” Mr Hall said.
“Now here’s a really good reason to step up on that promise of doing justice by Josh.”
“Josh isn’t coming home,” Ms Hall added.
“But he’s not coming home because that individual took a knife and used it in the worst possible way. Not once – six times.
“He’s then entered a justice system where he is then allowed real-world access to social media.
“He’s glorifying his gangster image.”
The posts have since been taken down with and the MoJ have said any offender caught with a phone in prison will face punishment, which could include additional time behind bars.
