A woman shot her husband and then hacked off his legs, arms, head and hands and stored them in a freezer before disposing of them at various locations around NSW, a court heard today.

Joyce Mary Chant, 57, denies murdering her husband, Robert Wayne Chant, 47, but admitted to hacking off his limbs in 1992.

She has pleaded guilty to improperly interfering with human remains.

The Crown prosecutor, Mark Hobart, SC, told the jury Chant shot her husband before dismembering his body.

"She cut off the legs and the arms and the hands and the head," Mr Hobart said.
