A woman has been charged with the murder of Joanne Martell, ABC reports.
Ms Martell was reported missing in May last year and her body was found on Mornington Peninsula by Police in January this year.
A week earlier, police said the 45-year-old had not been seen since she dropped her dog off at a friend's house.
Ms Martell had a teenage daughter and a son in her 20s, and lived a transient lifestyle around the Rosebud and Dromana area.
Homicide Squad detectives have now charged a 42-year-old woman from Ravenhall, in Melbourne's west, with one count of murder.
Police said she would appear at the Melbourne Magistrates' Court later today.
