Jovan Jojic, 22, of Sunshine, was charged with one count of murder, one count of conduct endangering life and one count of recklessly causing serious injury following the death of Saria Johnson, 20, on April 22.

Mr Jojic had been in the bedroom of the Currunghi Court house with a number of people smoking the drug ice and allegedly mucking around with the shotgun when Ms Johnson was killed, the Supreme Court was told.

Mr Jojic applied for bail last Monday but the application was adjourned until Tuesday to give the prosecution more time to produce further material in the case.

Justice Betty King said on Tuesday the latest forensic reports failed to advance the prosecution case, except to say gunshot residue was found on two pairs of tracksuit pants.

The judge said there was nothing in the new material to confirm Mr Jojic had fired the gun that killed Ms Johnson.

She told Crown prosecutor Damien Hannan it would be difficult to run a murder case against Mr Jojic given the material before the court.

The case could possibly be resolved as a manslaughter case, which must be distressing for Ms Johnson's family, Justice King said.

Mr Jojic was released on bail with strict conditions, including that his uncle provide a $160,000 surety; he not leave his parents' house from 7pm to 7am during the week and from 7pm Friday to 7am on Monday; he report daily to Sunshine police; not contact any witnesses and not leave Victoria.

"He's not going out socially," Justice King said.

She told Jojic that because of his alleged behaviour he had taken a life and if he did not abide by his curfew he would be returned to custody.

The court was told last Monday that Jojic had left the St Albans house after the April 7 shooting in shock and was not arrested until later that day.

The prosecution case was that the shotgun had been passed around in the bedroom where everyone had been in good humour before Jojic took hold of it without checking if it was loaded and then fired, killing Ms Johnson.

Justice King said she did not know what people were thinking when they played with guns and it was just stupid behaviour.

Police later seized clothes from Jojic's Sunshine home where he lived with his parents but were not sure if they were the same clothes he was wearing on the day of the shooting.

A number of pellets were lodged in the wall near where Ms Johnson's body was found.

Justice King described the prosecution case against Jojic as "very vague".

Jojic is due to appear in the Melbourne Magistrates Court on September 18 for a two-day committal hearing.
