Suspect enters not guilty plea

The man charged with the girls’ murders, Richard Allen, had his initial hearing and entered a not guilty plea, Carroll County Prosecutor Nicholas McLeland said.

He’s being held without bond and is set to return to court in January, he said.

“Per the court order, we cannot talk about the evidence that’s in the probable cause” affidavit, McLeland said.

The prosecutor would not say when Allen became a suspect or if he knew Abby or Libby.

McLeland said it’s “concerning” to him that Allen is a local Delphi resident. He called the arrest a “step in the right direction.”
