Eurydice Dixon's murderer to be sentenced

The man who raped and murdered aspiring Melbourne comedian Eurydice Dixon is about to learn how long he'll spend in jail.

Jaymes Todd stalked Ms Dixon, 22, for more than an hour before attacking her as she walked through Princes Park following a comedy gig on June 12 last year.

After the murder, the then-19-year-old bought a pie and coffee, went back to the Carlton North crime scene, and googled rape and pornography as well as stories about his victim.

Todd is due to be sentenced today but could one day walk free from jail as prosecutors have not asked for a life-sentence, citing his age, lack of prior convictions and early guilty plea.

He has autism and has been diagnosed with sexual sadism disorder since being in custody.

Before the murder Todd fantasised about violent non-consensual sex culminating in a woman's death, Victoria's Supreme Court was earlier told.

But the young man claimed the rape and murder didn't go as he planned, psychologist James Ogloff said.

Justice Stephen Kaye has previously indicated he would consider sentencing Todd to life without parole, if he found the man had premeditated the murder.
