The woman, who lost her baby in 2014 to cancer, had her central Wagga premises broken into in April when her laptop and a USB thumb drive containing the photos were stolen.

Wagga police then offered a "no questions asked" amnesty for the return of the items.

Speaking at a media conference on Wednesday, Inspector Adrian Telfer said they were "very pleased that this week we've been able to locate that laptop in Wagga".

"[We've] returned it to the mother, who was obviously very distraught through the loss of her child," Inspector Telfer said.

"That was aggravated by the fact that all of her photographs were stolen."

Inspector Telfer said the laptop's hard drive was completely wiped when they recovered it after appealing to the public.

"But some technicians were able to recover all those photographs for her," he said.

"It's been a number of months since we made that appeal, but we haven't forgotten about that property.

"Today's one of those stories that highlight really good police work."
