Update on the Delphi murders: A man has been arrested in connection with the 2017 killings of two Indiana teenagers.

In connection with the 2017 homicide of two young girls in Delphi, Indiana, a 50-year-old man has been booked into county jail. The unresolved case has been called the "Delphi Murders" and has sparked national interest and online discussion.

According to multiple reports, a guy named Richard Allen was booked into the Carroll County Jail on Friday in connection with the Delphi murder case. According to those sources, Allen, 50, has been transferred to a state facility for his protection.

Earlier, law police told WXIN that a significant discovery in the 2017 killings of Libby German, 14, and Abby Williams, 13, was in the works, with a news conference slated for 10 a.m. local time Monday.

Over February 13, 2017, the kids went missing while hiking on the Monon High Bridge. They were reported missing, and their remains were discovered the next day about noon.

For more than five years, the high-profile murder case has gone unresolved, spawning mountains of internet conjecture about the identity of the culprit.

Police produced two drawings of possible suspects. Audio and photographs from Libby German's phone were used as evidence, with police releasing an audio clip of a guy stating, "Down the hill."

A search warrant for the property where the corpses were discovered revealed new information regarding the inquiry, including the fact that the tape from which the "down the hill" audio came lasted 43 seconds, only a portion of which has been given to the public.

Furthermore, authorities discovered a huge amount of blood at the site, prompting them to suspect the offender had blood on their hands or clothing. According to court records, the suspect may have removed a "souvenir" from the murder scene and may have also "positioned and staged" the kids' bodies.

The investigating agent felt property owner Ron Logan's physical build matched that of the individual in the footage from Libby's phone, according to the request. His voice was "not incongruous" with the publicly published recording.

According to authorities, Logan also lied about his alibi. In the Delphi case, he was never listed as a suspect or prosecuted. He has subsequently passed away.

Authorities recently revealed that a social media persona called "anthony shots" engaged with Libby, fueling online curiosity.

Police linked that profile to a person called Kegan Kline, who was being investigated for child exploitation. He's never been charged or labeled as a suspect in the Delphi killings.

Kline has been interrogated regarding the matter. His trial on 30 charges of possession of child pornography is under underway.

Indiana State Troopers have been combing the Wabash River near Peru for evidence related to the case in recent months.
