This is what the affidavit revealed —
2/25/2017
ISP, Peru PD, and FBI executed search warrant
KAK was interviewed by ISP & FBI
KAK admitted that he created the a_shots profile and used it to communicate with an unknown number of underage girls
KAK was polygraphed and said he received approximately 100 sexual photographs and 20 masturbation videos from girls between the ages of 15 and 17
Apple iPod Touch, iPhone 3, iPhone 4, Samsung Galaxy S5, Samsung Galaxy S4, and Nextbook tablet were seized during search
2/27/2017
KAK contacted the ISP Cyber Crimes unit and said he had located his iPhone 5C
3/2/2017
ISP Cyber Crimes unit obtained iPhone 5C from ISP Peru
4/24/2020
A new lead ISP investigator was assigned to the case
6/12/2020
The new investigator received the digital forensic examination report from ISP Sergeant Chris Cecil and reviewed it
6/18/2020
Multiple law enforcement agents met with Miami County prosecutor
However, the affidavit
doesn’t say when the digital forensic examination was completed or by whom. It only tells us the new lead investigator (on
which case, btw?) obtained the digital forensics report from another ISP officer in June 2020.
The FBI has been heavily involved with this investigation (meaning Abby & Libby’s) since the very moment the girls were reported missing. They even pointed the ISP in the direction of KAK. Cellebrite could extract deleted data from iPhones long before 2017, and the FBI most certainly had access to the products and knew how to use them.
All that is to say… the ISP hasn’t provided a logical explanation for the delay, IMO.
