Travel blogger Kristen Olsen, accused of murdering husband and daughter, faces new charges: Biggenden

Police have filed additional charges against a 24-year-old woman accused of murdering a baker and his daughter in a fire at a rural Queensland property.

The bodies of 54-year-old Todd Mooney and his 10-year-old daughter Kirra were found on December 20 in a shed in Biggenden, 240km north-east of Brisbane.

Detectives last week charged Maryborough resident Kristen Leslie Olsen with two counts of murder and one count of arson.

Olsen’s case was heard for a second time at Maryborough Magistrates Court on Monday and she was not required to appear in person.

A Queensland Police spokesman said the prosecutor had additionally charged the creator of OnlyFans with one count of arson on a motor vehicle and two counts of arson on a building or structure allegedly committed in Tinana.

Olsen was also charged with theft, allegedly committed in Ban Ban Springs, about 30 km south-east of Biggenden.

The new charges related to alleged incidents separate from the murder charges.

The matter was adjourned until March 6 for final consideration. Olsen was remanded in custody and excused from appearing in person at the next hearing.

As part of the ongoing investigation, police have urged anyone who may have seen a white Holden Barina car with a prominent solar panel on the roof between Biggenden and Ban Ban Springs to come forward.
