The murders that puzzled police for five years has now gone to trial with the defense raising doubts about key elements of the prosecutions case.

The trial of Delphi murder suspect Richard Allen kicked off on Friday over seven years after the crimes were committed.

The 52-year-old Allen is accused of the murders of best friends Abigail Williams, 13, and Liberty German, 14, who were found dead in the woods in Delphi, Indiana on Feb. 14, 2017. The trial opened with horrific new details about the victims bodies as the defense tried to cast doubts to the jury on the prosecutions case.

Allen is a married father of five, and was arrested five years after the crimes were committed after police linked a bullet found at the crime scene to a gun he owned. The murders baffled police for years and rocked the small town of less 3,000 before police eventually suspected Allen of committing the murders.

Prosecutors opened their case by revealing new details about the day that Williams and German’s bodies were found in the woods on a snowy February day.

“You’re going to see the crime scene,” prosecutor Nick McLeland told the Jury, and added that the state will prove that Allen is the “bridge guy,” the person seen in William’s last SnapChat, before the girls were found murdered.

“It was a gruesome scene. Libby was completely naked. Her throat was cut, blood all over,” McLeland said. Abby’s throat was also cut.”

Williams was found wearing Liberty’s clothing, while other articles of the girls clothing was found dumped in a nearby creek, McLeland added.

“[The] last face the girls saw [was Allen’s],” the prosecutor said.

McLenland described the girls friendship as more than that, he said they were sisters. ‘”[They were] always together, really more like sisters,” McLenland said.

The prosecutor highlighted Allen’s confession to law enforcement and alleged that he knew details “only the killer would know,” according to local Fox affiliate WXIN.

Allen’s defense team countered by saying that the states case was riddled with inconsistencies. There arguments centered around the theory that the girls were killed at a different location and the killer dragged them to the location they were found by police. Allen was arrested for the killing after police linked a .40 caliber bullet to a gun that Allen owned in 2022.

One of Allen’s attorneys, Andrew Baldwin, argued that police often use the same caliber bullet found at the crime scene. He added that investigators never questioned officers if one of the bullets in their guns was missing.

Baldwin also argued that the owner of the land where the girls were found also has guns that contained .40 caliber bullets.

“You’ll see with your own eyes – Please wait, Richard Allen is truly innocent,” the defense attorney told jurors. Baldwin also addressed the hair that was found on Abigail’s body arguing that the DNA did not match Allens. He claimed that the hair found on her seemed to possibly match a female relative of Liberty’s, according to the U.S Sun.

“In seven years, they never turned over the mother or sister’s hair to be tested for DNA,” the attorney said.
