Two distinct sketches of potential suspects were published by the police. Police released an audio recording of a man saying, "Down the hill," as part of the audio and photographs from Libby German's phone that was considered to be crucial evidence. Court records uncovered by the 'Murder Sheet' Podcast over the summer revealed an FBI agent thought there was good reason to investigate Ron Logan's property, the owner of the property where the girls' bodies were discovered. On March 17, 2017, the property was searched by the authorities. Logan's voice and physical characteristics matched the evidence gathered from their phones, according to court filings. On the day they vanished, Logan also gave a false account of his whereabouts. However, a search of Logan's property turned up with no proof that he was connected to the killings and he was never named as a suspect or charged in connection with the Delphi case. He has since died.

Additional information regarding the inquiry was revealed by the search warrant, including the fact that the recording in which the "down the hill" audio was first heard initially lasted 43 seconds, only a portion of which has been made available to the general public. Investigators concluded that the culprit would have blood on their hands or clothing because of the enormous amount of blood they discovered at the site. The person may have "positioned and staged" the bodies of the kids as well as collected a "souvenir" from the crime scene, according to court records. They also looked into Kegan Kline, a sex offender who allegedly operated a catfish social media account and may have been the last person to get in touch with Libby German. No arrests or charges were made regarding any person of interest.

The investigation, which has attracted national interest, has recently acquired steam, and Indiana State Police intend to inform the public about the alleged murderer at a news conference on Monday, October 31 at 10 am. 

Kelsi German, the sister of Libby German, tweeted. At the press conference on Monday, October 31, she stated that her family will provide an update.
