The 15-year-old boy charged with the manslaughter of pregnant Hobart woman Sarah Paino, is not expected to plead at the next scheduled court hearing.
Prosecutors asked for the case to be adjourned until next week, in hope that he would be ready to enter a plea.
Despite the delay the boy's lawyer said she doubted whether he would be ready next week because she was yet to receive all of the information relating to the charges, ABC News reports.
The teenager appeared at the Hobart Supreme Court on Monday morning.
The 24-year-old expectant mother was on her way home with her two-year-old son after dropping her partner Daniel at work in Hobart about 1am on a Friday night in January.
The mother-of-two's car was hit by a four-wheel drive which was allegedly stolen and driven by the boy through Hobart.

Following the accident, rescue workers fought to drag the young mother from the mangled wreckage.
It was too late to save Sarah, but there was still hope for her unborn baby – if they could only get them both to hospital in time.
‘This baby is just completely and utterly a miracle baby,’ says Dr Kate Field, an emergency specialist at Royal Hobart Hospital.
Meanwhile, Caleb's father is grateful that his son was even born.
‘I just thank my lucky stars that Caleb’s here,' says Daniel.
The couple's older son, Jordan, was pulled from the crash alive and uninjured.
The teenager has been in police custody since he was charged with manslaughter and motor vehicle theft.
In February Daniel was interviewed by Sunday Night and he told Melissa Doyle: "I loved her, still do and I don't think I am going to find —I won't, I won't I know it — anyone that will come close to her,"
"I don't think I ever really want to.
"She was as close to perfect as you were going to get.
"I'm not in denial that she's gone, I know she's gone and not coming back but I find it very hard day by day at the moment. So yeah it crushes me you know," the devastated father-of-two added.
