Homicide Squad detectives have charged a 36-year-old woman with murder after a male was located deceased in Tyabb on Sunday 22 October.
The woman will face an out of sessions hearing in Melbourne later this evening.
Two other men; a 52-year-old man from Crib Point who was arrested this afternoon, a 34-year-old man from Hastings, who was arrested yesterday, are still in custody and are assisting police with their inquiries.
The arrests follow the discovery of a body behind a building on the 11.7ha property on Dandenong-Hastings Road in Tyabb about 9pm on Sunday night. The body was buried in a shallow grave.
Forensics police laid down yellow markers pointing to possible evidence found at the scene, including a black glove in the driveway. A blue tent was set up at the rear, covering the body.
Up to 40 SES volunteers were called in by Homicide Squad detectives to line search the Tyabb property for clues before the body was removed on Monday evening.
On Tuesday, the dead man was identified as Hastings resident Jade Goodwin. Mr Goodwin, who was known to police, was a father of two daughters.
