Mr Hughes told the court on September 15, he then took Lundy into the house to help identify anything that may have been out of place or stolen.
Mr Hughes said Lundy was hesitant as they moved through the house, and on one occasion needed help to support himself.
He said after Lundy composed himself, they approached the master bedroom, where Mrs Lundy's body was found.
Lundy was quick to notice Mrs Lundy's jewellery box was missing, Mr Hughes said.
"As we got to the master bedroom he looked into the bedroom and his immediate words were, 'Where's the jewellery box?"'
Mr Hughes also recalled a comment Lundy made when they left the house.
"He made the comment in the group that 'I'm so glad they took the jewellery box, I'm pleased there is something stolen'."
Earlier today Mr Hughes told the court that all officers who entered the crime scene were wearing paper overalls, booties and gloves.
However, in video footage shown to the jury by defence lawyer David Hislop, some officers appeared to be wearing no protective clothing.
The jury of seven men and five woman was also shown photographs from the crime scene.
Mrs Lundy's body was pixelated, but the photos showed areas of the walls and roof of the master bedroom spattered with blood and tissue matter.
Mr Hughes told the court Mrs Lundy was "unrecognisable" from injuries she had sustained.
A window that was confiscated from the Lundy's home after the murders was also shown to the jury today.
The window was found to have traces of blood on it, and indentations where tools were used to "jimmy" the window open, Mr Hughes said.
This morning, the Lundy family's former cleaner said the air was "tense" just days before Mrs Lundy and Amber were found murdered.
Rowena Collett was a cleaner for the Lundy family for about three years, and would clean once a week, on either a Monday or Tuesday, between 10am and 1pm.
Ms Collett told the court things felt "tense" in the Lundy household the last time she cleaned their home on August 28, 2000.
"I felt tension in the air."
The trial continues.
