Richard Allen probable cause affidavit reveals unspent round from his gun was found near victim's body

DELPHI, Ind. - A Carroll County judge chose to unseal the probable cause affidavit for 50-year-old Richard Allen, a suspect in the 2017 deaths of 14-year-old Liberty German and 13-year-old Abigail Williams.

Judge Frances Gull released the following statement:

"The court finds that the public interest is not served by prohibiting access, and that the protection and safety of witnesses can be ensured by redacting their names from the affidavit and the defendant's personal information can be removed from the charging informations."

Allen was charged with two counts of murder while trying to kidnap the victims, the affidavit states.

The affidavit reveals an unspent round located near the body of one of the victims had been cycled through a Sig Sauer Model P226 pistol belonging to Allen.

Investigators found a .40 caliber unspent round less than two feet away from one of the victim's bodies, according to reports.

The round was unspent and had extraction marks on it, the affidavit states.

On October 13, 2022, investigators conducted a search warrant on Allen's house in Delphi.

During the search, police found a Sig Sauer Model P226 .40 caliber pistol in the home.

The Indiana State Police Laboratory performed an analysis on the Sig Sauer and determined the unspent round found near the victims had been cycled through Allen's pistol, according to reports.

Investigators confirmed the pistol was purchased by Allen in 2001.

On October 26, Allen voluntarily went to the Indiana State Police post and told investigators he never allowed anyone to use or borrow the Sig Sauer Model P226 firearm, according to the affidavit.

When asked about the unspent bullet, he told investigators he did not have an explanation as to why it was found between the victims, reports said.

The affidavit also detailed multiple witnesses who claim they saw a male on the Monon High Bridge trail on February 13, 2017.

One witness said that on that day, she saw a male walking away from the bridge wearing blue jeans that were muddy and bloody, according to reports. The witness said the male appeared to have gotten in a fight.

Other witnesses described seeing a vehicle that matched the description of Allen's 2016 black Ford Focus parked with its rear against a building near the trails.

Allen was interviewed in 2017 and told investigators he was on the trail between 1:30 and 3:30 p.m. on February 13, 2017.

Allen said he saw three females on the Freedom Bridge but did not remember specific descriptions and didn't speak to them.

He said he didn't see anyone on the High Bridge.

On Monday, lawyers for Allen requested his murder trial be moved at least 150 miles away from Carroll County because it would be difficult to form an impartial jury due to public scrutiny.
