A second woman charged over the hit-and-run death of a Queensland police officer was unintentionally carrying a weapon when she surrendered herself to police custody, her lawyer says.
Skye Anne Wallis, 33, from Caboolture, had her case mentioned briefly in Caboolture Magistrates Court on Wednesday after handing herself in late on Tuesday.
She is charged with murder, arson and unlawful use of a motor vehicle, and also charged with unlawful possession of a weapon at the time of her arrest.
Wallis's lawyer Hugh Stitt, who asked for her appearance in court to be excused, said outside court that Wallis was "unintentionally" carrying a weapon when she handed herself in.
"It's a tragic set of circumstances and our condolences go out to all parties involved," he told reporters.
Senior Constable David Masters, 52, died on Saturday after being struck on the Bruce Highway at Burpengary by a suspected stolen car.
The vehicle was later found burnt out in semi-rural Moodlu, about 17km from where Sen Const Masters was killed.
Police will allege Wallis was the driver of the car which fatally struck the officer.
Wallis was remanded in custody until her matter is due to be mentioned in the same court on August 19.
The Magistrates Court does not have jurisdiction to hear bail applications for people accused of murder.
Earlier this week, a 24-year-old woman, who was allegedly a passenger in the car, was charged with murder, arson and unlawful use of a motor vehicle.
Kari O'Brien, from Morayfield, was not present when her case was heard in Caboolture Magistrates Court on Monday.
O'Brien's case will return to court on August 2.
