Teresa Cormack's killer probably kept her red raincoat as a souvenir.
Detective Sergeant Brian Schaab, who arrested Jules Mikus for the murder and rape of the 6-year-old Napier schoolgirl in 1987, believes Mikus may have kept Teresa's schoolbag and her little red raincoat.
After Mikus' arrest following a DNA breakthrough thisyear, a specialist team seeking clues, including the red raincoat, dug up the yard of the house he lived in 15 years ago.
"He may well have taken [the raincoat and the schoolbag] as souvenirs, but we haven't been able to find them," Mr Schaab said.
Even before the attack on Teresa, Mikus was a sex offender.
He was convicted of four sex crimes as a teenager, and an attack on a 14-year-old schoolgirl three years before Teresa's killing.
He suffered sexual abuse as a child and is understood to be undergoing ACC-funded counselling for abuse.
Before this week's guilty verdicts, Mikus had not been convicted of a sexual offence for more than 15 years.
But Mr Schaab does not believe he would have stopped abusing.
"Obviously he wouldn't take his offending to the same extent but he would still be victimising people along the way, whether they be partners or families or whatever."
