Two men have appeared in court charged with the murder of a young Frankston man almost 12 months ago.

The 24-year-old man was found dead with gunshot wounds outside Frankston Hospital about 2.45am on December 22 last year.

Alan Armstrong, 61, from Hastings and Tyson Haver, 29, were remanded in custody this morning in Melbourne Magistrates Court after being charged on Monday.

Prosecutor Michelle Zammit told the court that police investigators preferred that the three accused be bought into court separately for their appearances.

The solidly built Haver entered first, wearing a black T-shirt.

His lawyer, Tony Hargreaves, said there were no custody management issues for his client who acknowledged magistrate Donna Bakos when she told him when the police brief would be served and that he would appear again in April.

A bearded and balding Armstrong was brought in next wearing a jumper and shorts.

His lawyer James Dowsley asked Ms Bakos to note that he was on two types of medication including a mood stabiliser.

Mr Dowsley also said Armstrong had a hernia that required treatment and asked that he be transferred as soon as possible to the Melbourne Assessment Prison.

Apart from murder, Haver is charged with nine other offences that include a charge of intentionally causing serious injury and recklessly causing serious injury to two separate men at Somerville.

Both offences are on the same date as the alleged murder.

He is also charged with four firearms offences and two charges relating to marijuana allegedly committed in April this year.

Armstrong is also charged with intentionally causing serious injury to a man at Somerville.

Early this afternoon, Haver’s defacto partner Adalia Ottobre, 30, appeared in court charged with offences that included attempting to pervert the course of justice and making a false statement to impede the prosecution of Haver.

The first charge alleges that she provided a false alibi over the alleged murder.

Ms Zammit said that police did not oppose bail for Ottobre who has no prior convictions and that any issues of her being an unacceptable risk could be alleviated with special conditions.

These included reporting to police three days a week, surrendering her passport and not associating with Armstrong or another man connected with the investigation.

Mr Hargreaves said Ottobre had been in a relationship with Haver for nine years and the couple owned a property together.

Ottobre, who also faces firearms charges, will also appear at a committal mention hearing in April.

An earlier version of this story suggested the men charged over the death were father and son. This was incorrect.
