A woman accused of murdering her former lover in Bacchus Marsh will remain in jail after failing to show she knew nothing about the crime.
Hong Kong woman Yu Tung Lo factory reset her phone the morning after her former lover was shot and killed, police allege.
The 26-year-old was refused bail in the Victorian Supreme Court on Thursday and will remain in custody indefinitely until there is a trial.
Lo has been charged with murdering Bacchus Marsh man Paul Hogan, who was allegedly shot dead by her friend Daniel Duhovic on May 24.
Police say Duhovic, 33, shot Mr Hogan in the head as he sat in his parked van.
Lo had asked Duhovic to pick her up and help move her belongings from Mr Hogan's house, the court heard.
The Crown says Lo texted Duhovic the night before the murder to say she wanted Mr Hogan dead.
Detective Senior Constable Glen Scharper told Lo's bail application Lo sent a text that said: "I want to kill it."
"She directly encouraged Duhovic to shoot the deceased," said crown prosecutor Kevin Doyle.
Defence counsel George Georgiou SC said Lo should be released on bail because the prosecution had a "weak" case.
"There's no evidence she was even aware of him being armed," he said.
Det Sen Const Scharper alleges Lo erased data that may have linked her to Mr Hogan's murder by performing a factory reset on her phone shortly after the shooting.
In a record of interview with police after she was arrested, Lo also denied any knowledge of the shooting and her friendship with Duhovic.
Police say the pair had been in a sexual relationship shortly after Lo arrived in Australia in June 2015.
Justice Robert Redlich said he could not grant Lo bail based on the Crown's evidence before him.
"She went to quite extraordinary lengths to conceal the nature of her association with Duhovic," he said.
"She concealed her presence at the scene of the shooting and denied any knowledge of the shooting."
Lo has been remanded into custody until a possible trial, which is not expected to take place for another 20 months.
