James Adams and Robin Turner will stay in custody. Both are charged with concealment of a homicide and dismembering a human body.
The judge gave the state more time to file petitions for denying pretrial release.
The two were arrested last week, days after the remains of 38-year-old Dalewayne Turner were found.
Boaters said they were on the lake in in Cumberland County, attempting to move what they believed were dead fish, when they found part of a human arm.
Turner is due back in court on Thursday and Adams is due back in court on Friday.
