We're ending our live coverage after a 15-year-old was sentenced to 13 years in prison for the murder of 12-year-old Leo Ross in Birmingham.

You can read our full story here, but here's a summary of the key points from today.

• Mr Justice Choudhury KC said he intends to lift reporting restrictions to allow the defendant to be named, but delayed that by 24 hours to allow a possible appeal
• Leo's biological mother was in tears as she told the court: "If love could have saved Leo, he would've lived forever."
• His foster father said it broke his heart he had not been there to protect him
• Leo's killer was described as a "young man with formidable mental health problems" by the defence
• In passing sentence the judge said there was evidence the killing was planned and that the defendant got pleasure from seeing the consequences of his actions

Speaking after the sentencing today, Leo's foster family, the Westons, said: "While we acknowledge the court’s decision today, it marks neither closure nor healing."

They described the court's decision as "simply another step in a journey of grief that began the day we lost Leo".

"No sentence can ever undo or compensate the loss of Leo nor return him to us. Our family will live with this pain forever, they said.

The Westons also said: "Our focus remains on remembering who Leo was, not how he was taken from us."

Det Insp Joe Davenport, who led the investigation into Leo's murder, said it had been a "tragic and random act of violence which killed an innocent young boy".

He said there was no indication Leo and his killer knew each other, so it had been a "totally random attack".

"From our investigation, it seemed he liked to cause violence before calling the police and watching the chaos he had caused," he said.

He described the killer as a "truly dangerous individual" and added: "We will likely never know why he decided to attack Leo, who was completely innocent."

This is a photo of the murder weapon, released today by West Midlands Police.

The force said that after the stabbing, the killer tried to throw his weapon into the river but it landed on the river bank.

The knife was later recovered by police with the killer's DNA on it as well as the DNA of Leo Ross.

"That proved to be the critical evidence in the case," said Det Insp Joe Davenport.

We are hearing now from Leo Ross's foster family and from Det Insp Joe Davenport.

They've told us an online fundraising appeal after his death has paid for 37 bleed kit cabinets and is now paying for knife crime workshops.

The biological mother and father of Leo Ross have left the court without saying anything, but we are expecting a statement to be read out on their behalf.

So we are waiting for Det Insp Joe Davenport of West Midlands Police.

A reminder that in this case, the judge has agreed to lift reporting restrictions, to allow the defendant to be named.

But the judge has granted Birmingham Children’s Trust 24 hours to appeal against the decision.

So we can’t name him before 13:00 tomorrow and if an appeal is successful, he might not be named at all.

In cases heard before youth courts, anonymity is automatic. Similar orders are routinely made when juveniles appear before adult courts as in this case. But they can be lifted, especially following a conviction in serious cases.

Leo Ross's killer has now been taken down to the cells and the judge has concluded by offering his condolences to his family.

It was "hard to imagine what it must have been like" to receive the news, he said.

Mr Justice Choudhury KC has repeated to the killer of Leo Ross that he will serve a minimum term of 13 years in jail, reduced by time already served on remand.

He added that he would not be released at the end of that period unless the Parole Board found it was safe and appropriate to do so.

The judge has indicated that the planning of the crimes and the selection of the victims would add two years to the length of the sentence,

But that would be reduced by mitigating factors including his guilty plea, he said.

He has also been speaking about the sentences appropriate for the three attacks on women before the murder of Leo Ross.

Addressing the defendant's mental state, the judge said: "You knew and were aware of the consequences of your actions."

"You were thinking coolly and rationally," he said.

The defendant's young age had already been taken into account, he added.

The judge has said he the attacks carried out by the defendant were deliberate and planned.

He said he did not accept the defence arguments that his mental state prevented him from planning the attacks.

The judge is explaining that the automatic sentence for murder is "life at His Majesty's pleasure", and setting out the legal guidelines which led to the 13-year minimum he had already indicated.

The judge says Leo's killer chose him because he was a smaller boy and "in your usual cowardly fashion you attacked him".

Afterwards, he said the defendant cycled around the park, telling people a boy had been stabbed.

He told the defendant he appeared to get "pleasure from seeing the consequences" of his actions.

The judge has said that by the time of the boy's third attack on a vulnerable elderly woman, a pattern had been established.

"You were riding around the park looking for a victim," he said

Leo’s foster family is in tears as the judge is reading out his sentencing remarks.

There has been no emotion from the defendant.

The judge has also been speaking about the impact of the attacks on three elderly women in the park in the days before Leo Ross's death.

He said he had seen photos of the injuries inflicted.

"The savagery required to attack such injuries" had been "hard to imagine" he said.

The judge is reading out the defendant's guilty pleas and the circumstances around Leo's death.

"You are still a child, only 14 years old at time of offences," he tells the defendant.

But people would struggle to think that "what you did over three days in January last were the actions of a child".

He said Leo's family were enduring a "living hell" now.

The judge at Birmingham Crown Court has begun formally delivering his sentence.

Mr Justice Choudhury KC told the court the defendant had been "engaged in a campaign of violence against several people."

He said his crimes had robbed Leo Ross of his future. You can watch his remarks live at the top of the page.
