Police have charged a 22-year-old man with one count of murder over the disappearance of missing Victorian mother Samantha Murphy.
Detectives from the Missing Persons Squad have been investigating since the mother-of-three failed to return from an early morning run in the regional city of Ballarat.
While much of the timeline remains unclear, this is what police say they know about the alleged murder.
