On Wednesday, it was also revealed two other teen boys - aged 17 and 16 - who were under investigation over the alleged murder of Lovell are facing stealing charges related to a separate incident on the afternoon of Boxing Day, December 26.
They have been released on bail ahead of their appearance in Brisbane Children’s Court at a later date.
7NEWS understands one of the boys was responsible for the stabbing of a man in his St Lucia home in Brisbane last year.
The then 15-year-old was charged with attempted murder, was sentenced and has since been released from custody.
It is also understood one of the boys was arrested on Christmas Eve this year and charged with multiple offences.
He was released on bail despite police objections on Boxing Day, hours before he allegedly stabbed Emma Lovell to death.

The social media profiles of the boys show multiple posts of them and associates travelling in high speeds in stolen cars.
Multiple members of their families have called for them to be “free”, on social media posts.
Queensland’s Liberal National Party has again called for breach of bail to be made an offence, so young offenders are imprisoned for failing to stick to court-ordered conditions.
Shadow attorney-general Tim Nicholls said jail time wasn’t the only answer, but there needed to be a deterrent for repeat offenders.
“There needs to be punishment, and the community needs to feel safe at the moment,” he said.
“I can tell you the community out there is screaming that they’re not being kept safe.”
Youth Justice Minister Leanne Linard said the last time breach of bail was a crime, it didn’t result in any child offender serving any extra time behind bars but the current presumption against bail was more effective.
“I cannot provide any guarantee that that will mean there will never be any more crime but we will do everything we can, always, in our power, to make sure that the absolute weight of the law comes down on people who break the law,” Linard told reporters on Tuesday.
