Delphi murders: Everything we know about suspect Richard Allen as he is pictured for first time since arrest

The 50-year-old married man arrested on Friday in connection with the 2017 Delphi murders has now been pictured for the first time – more than five years on from the double slaying of teenage best friends Libby German and Abby Williams.

Richard Matthew Allen, from Delphi, Indiana, was taken into custody at around midnight and booked into Carroll County Jail. He has since been moved to a state facility for his own safety.

Local outlet FOX59 has now obtained a state-issued photo of Mr Allen, with a government source confirming that it depicts the man now behind bars.

The photo bears some likeness to the police sketches of the suspect which were released to the public over the course of the investigation – while the teenagers’ killer remained at large.

It is currently unclear what the accusations against Mr Allen consist of but law enforcement sources have described it as a “major development” in the high-profile case that has rocked the small, close-knit community of Delphi and gone unsolved for more than half a decade.

Libby’s sister Kelsi German tweeted on Friday before the arrest was made public that “today is the day” they had been waiting for.

“Just know how grateful I am for all of you. No comments for now, any questions please refer to the Carroll county prosecutor’s office. There is tentatively a press conference Monday at 10am. We will say more then. Today is the day,” she said.

Indiana State Police and members of the victims’ families are slated to hold a press conference on Monday morning to provide an update on the case.

Before his sudden arrest on Friday, Mr Allen’s name had never before been publicly linked to the murders.

Here’s what we know about him:

Who is Richard Allen?

It is not clear what information has led to Mr Allen’s arrest now, more than five years on from the 2017 slayings.

In August, Indiana State Police were spotted searching the Wabash River in Peru – around 40 minutes east of Delphi – in connection to the case.

At the time of the murders, Mr Allen would have been 44 years old.

The 50-year-old is a local resident of Delphi, where the teenage girls lived with their families.

According to online records, Mr Allen has lived in Delphi since at least 2006, and in Indiana his whole adult life.

He is married and works as a pharmacy technician, receiving his most recent pharmaceutical licence in February 2018 – one year on from the murders.

A local resident told Fox59 that Mr Allen currently works at the local CVS store – coming into contact with members of the community as part of his job.

“When I will go into CVS as a customer myself, he would say ‘do you need any help?’ I would be like ‘no’,” said Chandler Underhill, the manager of the local Brick & Mortar Pub, where he said Mr Allen was a regular.

“Just like a normal guy that I’ve seen for the last couple years, not really thinking anything.”

Mr Underhill said that Mr Allen always seemed “normal” when he would come into the pub where he works.

“I would talk; he wouldn’t say much. He seems like a normal guy,” he said.

“One of my servers was telling me that he wouldn’t speak much.”

Mr Allen appears to have no prior criminal record.

However, the Carroll County Jail record lists Mr Allen as also going by the alias of Craigh Ross Rentfrow.

What happened to Libby and Abby?

Libby and Abby went missing on 13 February 2017 after they set off on a hike along the Monon High Bridge Trail in Delphi, Indiana.

Their bodies were discovered the next day in a wooded area around half a mile off the trail.

For years, police have refused to say how the girls died and have revealed few details about the crime scene.

However, shocking new details about the murders came to light in a search warrant application obtained by podcast The Murder Sheet and shared with The Independent back in May.

The warrant, filed by an FBI agent investigating the murders back in 2017 and partly redacted, was to carry out a search on the home of a local man Ronald Logan.

In it, the agent revealed that the girls had lost “a lot” of blood during their deaths and that their killer is believed to have moved and staged their bodies, before taking some sort of souvenir from the scene.

For the first time, the warrant also revealed that the teenagers had been killed by some type of weapon. The word for the weapon was redacted in the document.

The murderer would have been covered in the victims’ blood in the aftermath of the slayings due to the “large amount of blood was lost by the victims at the crime scene”, it reads.

“Because of the nature of the victim’s wounds, it is nearly certain the perpetrator of the crime would have gotten blood on his person/clothing.”

Chilling footage of suspect

On the day the girls went missing, Libby had posted photos on Snapchat of her and Abby walking along the trail.

The happy image of the two best friends is believed to be the last photo of them before they died.

In a move that propelled the investigation forward, Libby also captured a grainy video on her phone of a man dressed in blue jeans, a blue jacket and a cap walking along the abandoned railroad bridge.

Investigators released a grainy image from the video and a chilling audio of the man telling the two girls: “Go down the hill.”

Investigators have long suspected that this man is the girls’ killer and have praised the girls for documenting the video as evidence.

Up until now, the man has never been identified.

Police gave the description of the man as a white male aged between 16 and 40 years old, between 5’ 6” and 5’ 10” in height and weighing between 180 and 200 pounds.

Multiple police sketches were circulated of a man matching the description of the man in the footage.

Other names tied to the case

The arrest of Mr Allen marks the very first time his name has been publicly tied to the unsolved murders.

Over the years, authorities have honed in on several other men.

A 27-year-old Indiana man fell under the spotlight last year when the online account he used to groom underage girls online was tied to the teenage victims. His home had been searched on suspicion of child porn charges just two weeks after the 2017 murders.

In December 2021, Indiana State Police announced that officials had “uncovered” a fake online profile called anthony_shots.

The profile was used from 2016 to 2017 on platforms including Snapchat and Instagram and used photos of a known male model, portraying him as being extremely wealthy and owning numerous sports cars.

Investigators said the person behind the account was Kegan Anthony Kline, 27-year-old man with addresses in Kokomo and Peru, close to Delphi.

According to an affidavit, Kline posed as the model in order to groom underage girls and get them to send nude photos and their addresses and try to get them to meet him. The male model whose photos were used had no connection to the case.

Kline was arrested on charges of child sexual abuse images and child exploitation tied to the account in 2020.

He allegedly admitted to investigators that he groomed underage girls online.

The affidavit said that Indiana State Police and the FBI carried out a search warrant on 25 February 2017 - less than two weeks after Abby and Libby were murdered - at Kline’s home in Peru after tracking down the user of the anthony_shots profile to the property.

Kline allegedly told investigators he would use social media accounts to talk to underage girls and had exchanged messages with and received about 100 sexual photos and about 20 sexually explicit videos from around 15 underage girls.

However, he denied any knowledge or involvement in the two teenagers’ deaths.

Kline was charged with 30 felonies in 2020 over the case.

The documents, filed in 2020 and heavily redacted, do not mention the murders of Libby and Abby and he was not accused of involvement in their deaths.

Libby’s grandmother Becky Patty told The Independent in December that the teenager had never mentioned speaking to anyone online prior to her death and that there had never been any indication that the two girls had arranged to meet anyone online the day they were killed.

Investigators urged anyone who had communicated with, met, or attempted to meet the individual posing as anthony_shots to come forward with information.

Prior to this, Ronald Logan had previously been on police radar, according to the 2017 search warrant application.

Mr Logan owned the land on which Libby and Abby’s bodies were found and his home was just 1,400 feet from the crime scene.

The warrant application cites multiple complaints that he was violent towards women and that he owned multiple weapons, including handguns and knives.

Mr Logan also allegedly lied about where he was at the time that the teenagers disappeared, claiming he was out of the area with a friend on the afternoon of 13 February when cellphone location data actually placed him in the area around the trail.

The document also says that his voice was “not inconsistent” with the man captured in the video by Libby.

Mr Logan was never charged and he died in 2020, before the case was solved.

It is currently unclear if Mr Allen has any connection to Mr Logan or Kline or to the anthony_shots account.
