A magistrate has criticised a delay in finalising expert reports in the case against the man accused of murdering young comedian Eurydice Dixon.

Jaymes Todd, 19, who is accused of sexually assaulting and killing Ms Dixon in Carlton North in the early hours of June 13, appeared before Melbourne Magistrates Court on Wednesday via video link from custody, charged with one count of murder and one of rape.

The court heard investigators were yet to receive pathology and DNA reports. The hold-up meant Mr Todd's lawyers were unable to request a list of the witnesses they wanted to question at the hearing that determines whether the teenager stands trial.

Prosecutor Christina Teague said the pathologist handling the case had been overworked in recent months and was apologetic about not completing the reports, but had now made doing so a priority.
