A problem crocodile that ate dogs and threatened passersbys has been removed from a remote town in the Northern Territory.

Police and wildlife rangers removed the almost four-metre long saltwater from its home at Baines River in Bulla yesterday afternoon. 

Floods earlier this year had brought the crocodile into the waterway, where it has been notoriously stalking and lunging at children and adults living nearby since.

"The crocodile had also reportedly taken multiple community dogs," police said.

Police said the crocodile was shot following consultations with community members, traditional owners and wildlife officers.

Children were given an opportunistic safety lesson and the animal was taken into the community and prepared for a feast in a traditional manner.

"There's never a dull moment in remote policing," police commander Kylie Anderson said.

The Northern Territory contains large and potentially dangerous crocodiles, according to the Department of Environment Rangers, Parks and Water Security.

Locals are urged to be crocwise and only swim where there are designated swimming signs.

People suffering from depression are benefitting from a more targeted version of an existing brain stimulation treatment.

Transcranial Magnetic Stimulation (TMS) delivers magnetic pulses to a patient's brain through a robotic coil placed on the exterior of the scalp. The pulses stimulate nerve cells involved in a person's mood.

Experts say the treatment provides another option for medication-resistant depression patients like Beau Jones.

"Depression at the worst of times is lethal and at the best of times is awful," Jones said.

Jones has been suffering from depression for 15 years and underwent TMS as an alternative path to treatment after his medication stopped working.

"It's definitely improved my mental health," he said.

"The situations I find myself in are not as intense or dark as they had previously been."

In standard TMS treatments, all patients receive magnetic pulses to the same area, but now the University of Melbourne and Queensland Neurostimulation Centre are developing a more targeted approach.

Researchers like Dr Robin Cash from the University of Melbourne use an MRI scan to map specific areas in each patient's brain that are triggering the depression.

The TMS is then sent to that spot with a millimetre of allowance.

"What we're doing is a precise targeted approach that's based on a brain scan," Cash said.

"Our initial data suggests up to 65 per cent of individuals respond to this personalised and targeted therapy." 

Luca Cocchi from the Queensland Neurostimulation Centre explained that the robotic coil sends up-to-date information to the machine.

"We will have a robot that will use information from the brain of the participant who will very precisely and consistently deliver the stimulation."

Victoria Police officers have spent the past two days searching the Ballarat area for missing mother Samantha Murphy, a fortnight after officers discovered her phone on the edge of a dam.

The 51-year-old mother was last seen leaving her home on Eureka Street in Ballarat East to go for a run in the Canadian State Forest on the morning of February 4.

She has not yet been found, but on March 8, 22-year-old Patrick Orren Stephenson was charged with her alleged murder.

Officers spent today and yesterday undertaking another "targeted" search in the Ballarat area as part of their investigation into her disappearance.

Missing Persons Squad detectives and a range of specialist police resources were involved in the search.

Police advised about 5pm that the search had concluded and said officers would not continue searching tomorrow.

"Since February, police have regularly undertaken a range of enquiries and small-scale searches as part of the current investigation," a statement from police said.

"Samantha's family has also been advised of the search.

"We are not in a position to supply further specific details of the operational activity at this time.

"A number of items located during a search in Buninyong on 29 May are still being forensically assessed. There are no updates on this process."

Police discovered Samantha's iPhone by a private dam near Slaughterhouse Road, south of Buninyong, on May 29.

The dam was just five kilometres away from the phone tower where her mobile last pinged. 

Her husband Mick Murphy was called after police made the discovery. He told 9News he immediately knew it was hers. 

It's hoped data from the device can lead them to Samantha's body.

Murder accused and two alleged accomplices on trial in High Court at Whangarei

Jurors have been asked to put themselves in the shoes of an airline pilot accused of killing two campers when they retire to decide whether he is guilty of their murders.

Greg Lynn's barrister Dermot Dann KC asked a Supreme Court jury of 14 on Wednesday to contemplate what they would have done if their improper gun storage had led to the deaths of two people.

"He thought he was going to be blamed for the deaths and he was 100 per cent correct," Dann told the court in Melbourne.

"He thought he was going to be wrongly blamed and he is being wrongly blamed."

Lynn is on trial charged with two counts of murder over the deaths of campers Russell Hill and Carol Clay in Victoria's alpine region in March 2020.

The 57-year-old told police, and the court, that the deaths were accidental.

Lynn claims Clay was shot in the head after a struggle between the two men as he tried to get his shotgun back from Hill, who he said took it from Lynn's car.

Hill died during a second struggle over a knife, when Lynn claims he was trying to defend himself.

Prosecutors told the court on Tuesday this story was a "fanciful" work of fiction and that Lynn had one year and eight months to concoct a script about what had happened at Bucks Camp that evening.

But Dann has taken aim at gaps in the prosecution's case during his closing address, labelling it "a shambles", "desperate" and "hopeless".

"You're being asked to find a man guilty of murder, there's on the prosecution case zero factual foundation, zero motive, just a complete blank. Does that sit well with any of you?" he asked the jury on Wednesday.

Dann told the jury his client had admitted the charges he was guilty of – improper firearm storage and destruction of police evidence by burning the crime scene and bodies of the two campers.

He said a gun storage charge would have cost the Jetstar pilot his career, as Dann asked jurors what they would do in that situation.

"He's left the gun in the car, the magazine in the car, it's unsecured and he's failed in his storage of the gun," Dann said.

"You've got to put yourself in Mr Lynn's shoes, presuming of course that he's innocent.

"This was a disaster… of course he's thinking about himself, of course he's selfish, of course he was callous."

As his barrister gave his address, Lynn's wife Melanie and son Geordie sat in front of him and behind his lawyers on Wednesday, holding hands and nodding along in full view of the jury.

Dann will finish closing the defence case on Wednesday afternoon.

Justice Michael Croucher will then outline details of the charge to the jury, before they are sent away to deliberate on a verdict.
