Classes have resumed at the University of Idaho. It's been two weeks since four students were found stabbed to death inside their home and seemingly little progress has been made in finding the killer.

Even though security has been tightened on campus, many students are not returning, preferring to complete the semester through remote learning. Meanwhile, investigators are sifting through more than 700 tips, 100 pieces of evidence, and 4,000 photos looking for evidence.
