Murder charges over Qld fire deaths

The local bakery owner was due to marry his fiance on December 28. 

Investigators initially believed the pair died in a tragic accident before post-mortem results steered police to treat the incident as a homicide.

Police have charged a 24-year-old Maryborough woman with two counts of murder and one count of arson. 

She is expected to face Maroochydore Magistrates Court on Saturday.

Investigators are appealing for anyone who may have seen a white Holden Barina wagon with a distinctive solar panel on the roof in the area around the time of the fire to contact police.
