A 22-year-old man has now been charged with the murder of missing Melbourne mother Samantha Murphy.
The man was arrested yesterday morning and interviewed by police before being charged with one count of murder.
Authorities said he would face Ballarat Magistrates Court this afternoon.
Police said they were yet to recover a body and the investigation remained ongoing.
Murphy's husband, Michael, told 9News the situation ahead was a "whole [lot of] unknown".
"The family's going ok... I can't comment on anything at the moment," he said.
Murphy went missing on February 4 after leaving her Ballarat home for a run.
The last sighting came from CCTV footage outside her own home. She was wearing a maroon running shirt, black leggings, and an Apple watch.
Her home was close to the northern border of the Woowookarung Regional Park, or Canadian Forest, where she was known to run.
Multiple searches have been conducted, but she has not been found.
"Despite a significant investigation and extensive searches of the Canadian Forest area, no trace of the 51-year-old has been located," police said in a statement on Thursday.
"There are no further updates at this time and the investigation remains ongoing."
Officers have spoken to a number of people as part of their investigation into her disappearance, police said.
In late February, Detective Acting Superintendent Mark Hatt said it was most likely her disappearance involved one or more parties.
Police were doubtful she was still alive and had been looking at the possibility her body was moved from where she vanished, Det Supt Hatt told reporters on February 23.
Anyone who has information about Samantha Murphy's disappearance, including CCTV or dash-cam footage from the time she went missing, is urged to come forward.
"We understand that there is a continued high level of interest in this investigation and concern about Samantha's disappearance, however it remains critical that any speculation does not impede any aspects of the investigation," a police spokeswoman said on Thursday.
Murphy's disappearance sparked weeks of extensive searches around greater Ballarat area by trained emergency services workers and hundreds of concerned locals.
They combed through dense forest, private land and walking tracks.
Buninyong Police Station, which was originally a base for the search operation, was unattended on Thursday with the lights off and door closed.
A whiteboard with a map showing where the public could help search was long gone, and a sign on the door instructed anyone with information to contact Crime Stoppers.
Samantha Murphy has been described as mentally and physically fit and was training for an upcoming race by doing 15km runs.
Detectives have been working with telecommunications technicians to track the route she travelled, after confirming she had a smartwatch and phone on her.
Samantha Murphy and her husband Michael run a car repair business called Inland Motor Body Works at Delacombe, a few suburbs from their home.
News crews staked out the Murphy household near Eureka Street on Thursday, where Michael Murphy was seen walking into his shed before getting into his truck and driving away.
He told AAP that police had advised him not to comment to the media at this stage.
Michael Murphy and the couple's eldest daughter Jess previously issued a public plea to help find her.
"Mum, we love you so much and we miss you, and we need you at home with us," Jess told reporters on February 8 in Ballarat.
Police in Victoria can only hold people in custody after an arrest for a reasonable time before they issue charges, however the law does not state what a reasonable time is.
