A man has been charged with murder over a horror double murder on Victoria’s Mornington Peninsula.
Jackson Gilmour, 29, was sleeping at the house on Parson Street in Rye when a woman and a man broke into the house just after 4am on December 2.
Mr Gilmour, 29, and Charlyze Hayter, 19, were treated by paramedics for gunshot wounds but both died at the scene in Melbourne’s south.
It is believed Ms Hayter and a 24-year-old man broke into the property.
A female guest staying at Mr Gilmour’s home rushed to the bathroom and called police as he confronted the couple.
Ms Hayter then allegedly hit Mr Gilmour with a baton and demanded he hand over his wallet and other personal belongings as she rummaged through his drawers.
Mr Gilmour fatally shot Ms Hayter before he was allegedly shot by the male intruder who fled the scene in a vehicle.
