Russian national Vladimir Kondakov, 49, had been on the run since killing Albert Metlege and badly wounding his son Antony in a stabbing attack last Wednesday.

Kondakov was employed by the Metleges at the St Peters development.

Police said a man's body was on Sunday morning found at a park in Taren Point, in Sydney's south, by members of the public.

A crime scene has been established but the death is not being treated as suspicious.

The brazen daylight stabbing is believed to have stemmed from a workplace dispute between the three men.

When paramedics arrived at the scene, they found a knife still lodged in Antony Metlege's back.

He underwent surgery and remains in a stable condition at Royal Prince Alfred Hospital.

His father Albert died at the scene.

The vicious attack sparked a state-wide manhunt for Kondakov, who fled the scene and was last seen in Rockdale, about 6 kilometres from scene of his crime.

Kondakov was described as transient and without a fixed address.

Dog squads, riot officers and aerial units combed Sydney's streets looking for the 49-year-old.

NSW Police Chief Inspector Michael Merrett urged Kondakov to hand himself in and warned community members to be vigilant.

The body found on Sunday morning is yet to be formally identified.
