Coroner Alexander Ho’s inquest into the 2019 death of the 3-year-old continued in Invercargill yesterday.
Police concluded the boy had drowned after he was found face-up in an oxidation pond 1.2km away from his Gore home.
"We both noted that Lachie’s body was in perfect condition," they wrote in a joint letter.
Mr Hammond said Lachie’s father Paul Jones visited the funeral home and asked to check his son’s feet and legs for marks.
They did, and the witness said he did not see any damage to Lachie’s feet.
Constable Rachel Lean, who was involved in photographing Lachie’s body, also did not notice any unusual markings.
St John emergency medical technician Bernie Varaine described his attempt to revive Lachie.
She said she performed CPR for "quite a while" with no success.
Throughout the inquest there were allegations of foul play and Lachie’s body being stored in a freezer.
The volunteer said she did not notice anything that would suggest the toddler had been frozen.
"It was January, it was ... a relatively warm night and he was cold to touch and wet," the witness said.
"There was nothing inconsistent with a body coming out of the water."
An ambulance care summary recorded the boy was "floppy and unresponsive" and the witness said there were no obvious signs of rigor mortis or rigidness.
The officer in charge of the reinvestigation, Detective Inspector Stu Harvey, read his formal written statement yesterday.
He explained some of the main criticisms relating to the first investigation were the lack of scene examination and failing to establish a timeline, among other things.
A police dog handler also gave evidence yesterday in a closed court, which the media were excluded from.
Det Insp Harvey will be cross-examined today.
