A woman allegedly shot dead by her husband in a suspected murder-suicide had already packed her bags and was planning to leave, it has been revealed.

Krystel and James Paul, both 41, were found dead in separate rooms inside their Verbena Dr home in Mount Sheridan, Cairns, on Tuesday night.

The married couple’s nine-year-old daughter had fled the home to sound the alarm, banging at a neighbour’s door.

It’s now been revealed, according to Krystel’s friend, that the Queensland mother had been planning on leaving her husband before she was killed.

“She’d packed her and her daughter’s belongings in the boot and was literally about to leave,” the friend told prominent domestic violence advocate Sherele Moody.

Police are continuing to investigate the circumstances surrounding their couple’s sudden deaths, with Detective Acting Inspector Alina Bell saying they did not have a history of domestic violence or mental health issues.

“It’s always possible that things go on behind closed doors that family, friends and police are not aware of,” she said.

“But our investigations have indicated to date that there is no indication that there was any domestic violence within that relationship.”

The couple was not known to police.

Multiple firearms were found in the home, all registered to the husband.

According to police, the child had been “alerted to the incident occurring” before seeking help from family members and neighbours.

“That triple zero call occurred as a result of another family member calling us,” Bell said.

The child is currently in the care of family members, who are being given ongoing support.

“This is not only a tragic occurrence for friends and family, it also significantly impacts the whole of the community,” Bell said.

An investigation is ongoing.
