Murphy's mobile phone signalled a cellular tower in
Buninyong, approximately from her home, although signals from multiple towers are required to
triangulate the location of a mobile device. The SOS function of Murphy's
Apple Watch, which she was wearing on her run, was not activated. For several days,
Victoria Police (including the
Search and Rescue Squad,
dog squad,
Mounted Branch, and
Air Wing), the
Victoria State Emergency Service,
Parks Victoria and the
Country Fire Authority conducted an extensive search of the park and surrounding areas. The search initially commenced at Woowookarung Regional Park and nearby bushland; no sign of Murphy or her belongings were found and police ruled out the possibility of her having suffered a medical episode or leaving the area of her own accord. The search then expanded to the wider Ballarat area, including
Black Hill and
Brown Hill. After five days, the search was scaled back and the Missing Persons Squad took over the investigation. Members of the public, both local to Ballarat and from across Victoria, continued searching. By 23 February, police said they
suspected Murphy was deceased and believed "one or more parties" may have been involved in her disappearance. On 6 March 2024, Patrick Orren Stephenson, a 22-year-old male from
Scotsburn, was arrested in connection with Murphy's disappearance. The following day, he was charged with murder. The police hypothesis is that Stephenson, who was not known to Murphy's family, killed her at
Mount Clear. Stephenson's name was initially subject to a
suppression order. On 29 May, Murphy's wallet containing her
ID cards and mobile phone was found on the bank of an
agricultural dam during a targeted search of a property near
Durham Lead, approximately south of
Buninyong. Murphy's body has not been found. == Response ==
