Prosecutors have charged Gregory O'Bryan with the 18-year-old's murder, even though they still haven't found his body.
It's believed that the relationship between the two started on the Internet, and ended with their late October meeting.
That's why prosecutors seized both of their computers for evidence, which is where the FBI gets involved.
In a serious case like this in Louisville involving computer hard-drives, the federal government takes over. That's because they have special forensics investigators that many cities and states simply don't have.
O'Bryan faced a judge again on Dec. 2., sitting quietly during the five-minute proceeding that adds another step to the long road of determining his fate.
"We still haven't been able to find Andrew's body," Assistant Commonwealth Attorney Tom Van De Rostyne said during the court hearing. "So he's still missing. We're relying on the defendant's statement that he is dead, so we're relying on that, which is why we took the action against him."
The search for Compton in a Medora, Indiana landfill was called off after nine unsuccessful days.
While the computer hard-drives are expected to provide investigators with some clues, their collection of evidence doesn't end there.
"I can't go into what the specific items are, but there will be testing on things that we have obtained from Mr. O'Bryan's apartment and his vehicle," Van De Rostyne said during an interview with WAVE 3 News.
Despite the defense's push, the discovery, which is a case file containing substantial information about the case, hasn't been filed yet by the prosecution.
Prosecutors say that's normal in a complex case like this.
Both sides will be back in court in early January.
