Kristen Leslie Olsen, 24, was charged with arson and the murder of baker Todd Mooney, 54, and his daughter, Kirra, 10, on Friday and has had her case heard in a Sunshine Coast courtroom on Saturday.
Ms Olsen is accused of lighting a shed fire on a Biggenden property, north-west of Brisbane, that was owned by Mr Mooney, on December 20.
Detectives say Ms Olsen lives an hour north of Biggenden, in Maryborough, but has connections to the Biggenden area.
