The Tuesday arguments pitted the Denver Post against the parents of the killers and the Jefferson County (Colo.) Sheriff's Department, the Rocky Mountain News reported.
The killers' parents brought the challenge, arguing that tapes and records taken from their home are personal property and should not be released to the public -- even though much of the information was already seen by the media. The sheriff's department agreed.
However, the Denver Post argued the information should be available for public release via Colorado's Criminal Justice Records Act.
Rohrbough said the documents "shine a glaring light" on actions of the killers' parents and the sheriff's department, which has been investigated for allegedly covering up information, the newspaper reported.
