What KAK has said...
Kline said police told him that the anthony_shots account was the last to communicate with Libby German before her murder. When MacDonald asked Kline if he talked to German on Feb. 13, 2017, Kline said, "That's what they said. That's what the police told me."
Kline said he is not sure if the search warrant police served him with in 2017 was connected to the Delphi murders or the child exploitation and child 









case.
"I had no clue. I asked them, 'Hey, what is this about?'" Kline told MacDonald.
When asked if he had any recollection of talking to Libby, Kline responded, "No, not at all. I told them 100 times. I've done everything they've wanted me to, and it's like they're just harassing me."
MacDonald said that Kline told her he gave police a DNA sample and a hair follicle sample.
When asked if if he had anything to do with the murders of Abby and Libby, Kline responded, "Not at all." When asked again if he was involved in the killings, Kline answers, "No, 100% not."
Kline told MacDonald he doesn't remember communicating with Libby and does not believe he will be charged in connection with the Delphi killings."
What LE has said...
"...On Feb. 27, 2017, Kline contacted police, claiming he had located his iPhone 5. Investigators said they found images of females posing nude, but investigators could not determine their ages. Investigators also found much of the data from Facebook, Instagram, MeetMe, Snapchat and Twitter had been deleted. A review of the phone found that hours after police released him the day they searched his home, Feb. 25, he had uninstalled and deleted Snapchat and Instagram. The following day, MeetMe was uninstalled and deleted. The browser search history had also been deleted the morning of Feb. 27 before the phone was turned in to authorities."

Seems to me LE had KAK dead to rights in 2017 on child




charges. Only possible reason(s) that come to mind that they didn't arrest him is...
He was only found with pictures and not communications with minors.
Instead of bringing charges, KAK agreed to become a confidential informant to help LE "search" his "world" to try and find information on who the Delphi killer(s) were.
The original devices LE confiscated must have convinced them he was not an active person to person threat to children, meaning no meet ups or online contacts, just sitting in his home on the computer...and not sharing just downloading?
That last phone he himself turned in had a lot deleted from it including Snapchat and MeetUp apps. I'm wondering if that phone wasn't checked as well as the the others?
It's possible, I suppose, that KAK became a kind of trusted source? Maybe when fresh eyes reviewed things, that last under-inspected phone (that must have been hidden fairly well to escape the search warrant) was throughly restored and was the only one using the anthony_shots account? LE finds that on the fresh-eyes review and info and LE actions unfold?
I'm using the question marks because it's all just my supposing.
