This is not looking good in terms of having any idea who did this.

> Police do not believe the two surviving roommates were involved. They were home at the time of the attack.

> The Idaho State Police are analyzing DNA samples, such as bedding and nail clippings, from the scene. The coroner says it’s possible some of the DNA could be from the killer.

And I get it - cops hold back info to “catch” an unsuspecting killer who might not have their guard up:

> “What we hope they are doing is they have information that they’re withholding because they don’t want the person, whoever they eventually find, to know what they’ve been talking to the press. So they can use that as part of the investigation process,” said Wolf.

But my guess is the cops still don’t have any good leads or idea what happened:

> There are currently no suspects in custody. The murder weapon has not been found.

> Investigators are asking anyone who saw suspicious behavior, or has video footage or information about the attack to call their tip line at 208-883-7180 or email tipline@ci.moscow.id.us.

I hope they find the killer. This is beyond horrific what happened to those students. Maybe they can try the cell phone triangulation data that cops used to catch the Craigslist killer in Boston about ten years ago (and that the FBI has been using to figure out who was inside the Capitol on Jan 6).
