Key information about the Idaho murder suspect will be released following his extradition. Here's what might happen next, experts say.

Pennsylvania authorities announced on Tuesday that the man accused of killing four University of Idaho students would be extradited to Idaho, marking the start of legal proceedings against the suspect after more than a month-long investigation.

The suspect appeared at the Monroe County Courthouse in Stroudsburg, Pennsylvania, on Tuesday, where he waived his extradition rights. Within 10 days, he will be moved to Idaho, where he will make another court appearance — and where critical information about the suspect and the killings could be released, experts told Insider.

"He likely waived it because he is ready to be back in Idaho and have an appearance in court," Danielle Slakoff, an Assistant Professor of Criminal Justice at Sacramento State University, told Insider. "The Idaho law states that the probable cause affidavit — the document that spells out some of the evidence and circumstances leading to the arrest — cannot be released until he appears in court."
