I'm sorry, I didn't intend to convey that Klunder had been convicted of sexually assaulting anyone. Just that if hypothetical zip ties had carried his touch DNA on them, zip ties are a difficult surface for keeping touch DNA since they are slick and impermeable. Five months in the elements would probably wash off or degrade any touch DNA past the point of being useful.
If Klunder had been bleeding from a struggle with one of the girls, a dried blood droplet would be more likely to survive on a zip tie but I doubt that happened. Sadly, I think that each cousin was too afraid for her cousin to put up a fight.
Grainne Dhu, sorry but I didn't get to complete my original reply to your comment. It is possible that, if zip ties were used in E & L's abduction. They can be traced back to the same supplier or manufacturer. MJK, would have likely purchased industrial zip ties in bulk due to his occupation, imo.
Imo, the zip ties were only used by the investigator as an example. The COD & any other similarities would have also been very important, imo.

Forensic Cases: The Murder of Leanne Tiernan
Author: Suzanne Elvidge BSc (hons), MSc - Updated: 17 September 2013
In August 2001, a man walking his dog in Lindley Woods, near Otley, in West Yorkshire, found the body of 16-year old Leanne Tiernan, buried in a shallow grave. This was about ten miles from her home in Landseer Mount, Bramley, Leeds. She had been walking home from a Christmas shopping trip with her best friend in November 2000 when she disappeared.
In the largest search in West Yorkshire, the police searched around 800 houses and 1500 gardens, outbuildings and sheds on her route from the bus stop to her house, as well as searches of a three-mile stretch of canal, drain shafts and moor land.
Length of time since her death
The pathologist examining her body said that it had not been there since November. She had been strangled and her body stored at low temperatures in the intervening time.
Some of the cable ties used on Leanne Tiernan were of a type used almost exclusively by the Royal Mail, the patent company of John Taylor’s employer, Parcel Force.
