2 girls found murdered in Delphi, Indiana in 2017
DELPHI, Ind. (WLS) -- A judge said Tuesday she will take time to consider two important decisions in the case of two girls murdered in Delphi, Indiana.
One involves information in the case, the other, the suspect's freedom.
Despite the arrest and an initial court hearing for suspect Richard Allen more than three weeks ago, the evidence that led police to arrest him is still a secret.
On Tuesday, the judge said she will take time to consider the motion to unseal documents, but nothing was released and the judge did not say when she would announce her decision.
A prosecutor in court said they continue to investigate and have reason to believe Allen did not act alone.
The prosecutor also argued keeping documents sealed is key to the integrity of the ongoing investigation.
Allen's lawyer, Bradley Rozzi, argued the court should be transparent, and there should be disclosure of public records for several reasons.
Rozzi said this case has been highly publicized, and he thinks part of the reason why is the secrecy involved.
Carroll County prosecutor Nicholas McLeland wants to protect witnesses on both sides, mentioning that Allen's wife was forced to move and abandon their home.
McLeland presented multiple exhibits to the court, including a letter from Libby German's guardian and grandmother, Becky Patty, and an online petition that garnered 40,000 signatures asking to keep probable cause confidential.
But Rozzi thinks most of the threats are coming from social media and pose no significant risk, as the crime was over five years ago.
Last month, Indiana State Police arrested the 50-year-old in connection with the murders of teenagers Abby Williams and Libby German.
Their bodies were found near a hiking trail in Delphi in 2017.
But even before his arrest, court records were sealed at the request of a Carroll County prosecutor.
Investigators have since declined to release details as to what led up to the arrest and just how the girls were murdered.
This comes as the suspect is asking for the court to either reduce his bail or release him on his own recognizance, claiming prosecutors don't have enough evidence to prove his guilt.
Allen is due back in court for a bond hearing at 10 a.m. Feb. 17.
He did not speak at the hearing and wore a yellow jumpsuit, heavy chain and bulletproof vest. His wife and mother were in court.
