'Peace Came Over Me': Police Announce Arrest In Delphi Double-Murder Cold Case

A man has been formally charged in connection to a famous cold killing in Indiana, but police refuse to release many details in the major development of the Delphi double-murder case.

On Oct. 31, Indiana State police announced the arrest of Richard Allen, 50. He was charged with two counts of murder in connection to the 2017 murders of Abigail Williams and Liberty German in Delphi, Indiana.

The two girls were killed on Feb. 13, 2017, along a trail in a park. They went for a hike around 1 p.m. and met a man along the trail. The pair went missing and their bodies were found the following day.

Before her murder, German managed to record a short iPhone video of her and Williams' suspected killer as well as audio of his voice as he told the two: “Guys…down the hill.”

The case almost immediately became a significant one for True Crime fanatics. The killings became the subject of podcasts and books as people tried to solve the case. A grainy photo of the suspect helped spark many amateur investigations.

Police investigated the case but made no arrests for years. They also didn’t release many details about the investigation.

That continued in the announcement of Allen’s arrest as Carrol County Prosecutors Nicholas McLeland said “Per the court order, we cannot talk about the evidence that's in the probable cause [affidavit],” according to ABC News.

Investigators did not say when Anderson became a suspect or if he knew the victims. As FrontPageDetectives previously reported, Anderson was arrested last week and later formally charged in connection to the cold case.

Even though police made an arrest, officials are still asking anyone with information to contact authorities.

German’s sister Kelsi German posted on social media about the developments in the case.

“Thankful for everyone who has given me space and allowed me to process quietly for a couple of days. I see your messages, replies, posts, etc. They haven’t gone unnoticed. I appreciate all of you. I will respond tomorrow,” she wrote on Oct. 30.

She has shared news of the arrest but hasn’t commented on the announcement.

Indiana State Police Superintendent Doug Carter said he hoped the families found some peace with the arrest. He added the development brought him some closure as well.

"Peace came over me — and I didn’t expect that to happen,” Carter said.
