LOUISVILLE, Ky. (WDRB) -- A judge unsealed documents in the child pornography case of an Indiana man who's been linked to the murders of two young girls in Delphi, Indiana, five years ago.

Abby Williams, 13, and Liberty "Libby" German, 14, went for a hike on Feb. 13, 2017, on the popular Monon High Bridge Trail in Delphi when they vanished. Their bodies were found the next day, and the case remains unsolved. 

Kegan Kline, who faces 30 counts of child pornography, was linked to the teens after court documents reveal that investigators found chats, photos and other evidence indicating he had communicated with them shortly before they were killed.

According to a report from Fox59, the heavily redacted unsealed court documents in Kline's child pornography case reveal he had at least seven devices with evidence including images tied to the child porn case. The unsealed court documents also reveal that in some of the messages found on the devices another persona named "Emily Anne" would talk to teen girls about having sex with both Kline and his father.

Some images found on the devices depicted children as young as 3 in sex acts, the documents reveal.

Investigator said Kline was using a fake social media account using the alias "anthony_shots" to communicate with teens on Snapchat and Instagram. The account user posted profile images of a male model that portrayed himself as a wealthy man with sports cars in an effort to talk to young girls, solicit nude images and attempt to arrange meetings with them. 

Police said the male model used in the images was not connected to the crimes and that the accountholder used the images of him to create a false persona and hide his own identity.

Kline is not charged in connection to the Delphi murders and has not been named as a suspect, although he was interviewed by a state trooper and a sheriff's deputy about his communication with Libby, and his home was searched 12 days after their murders.

Investigators said he admitted to speaking to about 15 underage girls and getting images from "every one of them." According to the affidavit, he told investigators that the girls' ages ranged from 15-17, and he probably received 100 sexual images from the girls.

Kline remains jailed with a $265,000 bond on the child porn case.
