A male suspect has been apprehended in connection with the disappearance of an Australian woman whose case has captured national attention for the past month.

Samantha Murphy was last observed leaving her residence in East Ballarat, Victoria, to embark on a morning jog on 4 February. Despite an extensive search effort, authorities have failed to uncover any clues regarding the whereabouts of the 51-year-old mother of three.

On Wednesday, law enforcement took a 22-year-old individual into custody; however, no formal charges have been filed against him yet.

According to Victoria Police, the arrest occurred at the suspect's residence in Ballarat, approximately 115 kilometers (70 miles) northwest of Melbourne. They further stated that their investigation "remains ongoing."

On the day she vanished, Ms. Murphy was captured by security cameras in her driveway wearing a maroon running shirt and black leggings. Subsequently, when she failed to return later that day, authorities initiated a thorough search of nearby areas and reviewed extensive CCTV footage.

Ms. Murphy was known to frequent local bush areas known as Canadian Forest and Mount Clear, where hundreds of community volunteers have participated in search efforts.

The missing woman's phone, Apple watch, and headphones, which she had in her possession at the time of her disappearance, have yet to be located.

Her family has continued to implore the public for any information that may shed light on her case, characterizing her as a resilient individual who would be steadfast in her determination to return home.

"Mum we love you so much and we miss you. We need you at home with us. Please come home soon," her daughter Jess Murphy said.

Police have previously told the public they believe "another party" or "a number of people" may have been involved in the disappearance.

They also warned that it was "very doubtful" that Ms Murphy was "still alive".

"Unfortunately, given the time, and the fact we have found no trace of her, we do have severe concerns," Detective Acting Superintendent Mark Hatt told reporters on 23 February.

However, detectives have also appealed for anyone who sees Ms Murphy to come forward.

Too bad.
