Hours after police learned a masked man dressed in black had been seen making a getaway after the fatal stabbings of four University of Idaho students, authorities told the public there was no danger to the community.

Local police would later even go so far as to say the killings were an “isolated targeted attack” with “no imminent threat” – without explicitly saying why they’d reached that conclusion.

But new documents released this week revealed bombshell information about the mysterious small-town murder that has gripped the nation. The emerging details suggest that, from day one of the investigation, the Moscow Police Department had reason to believe a killer was on the loose.

So why didn’t the police continuously warn the frightened community?

It was “irresponsible” for Moscow police to tell the public there wasn’t a safety concern, said Michael Alcazar, a retired detective with the New York Police Department and adjunct lecturer at the John Jay College of Criminal Justice in New York City.

“One hundred percent there was a threat to the community,” Alcazar said.

But that sentiment isn’t fully shared by other crime experts. While seemingly incomplete and inconsistent information from police left many furious – including public outcry from one victim’s father – it’s part of the rigors that come with a high-profile case, one expert said.

“They’re not going to show their best cards,” Alison Sullivan, a retired police detective in suburban Hartford, Conn., said about the Moscow police’s oft-criticized strategy. “If you show your hands and let the public know you may have a suspect you’re monitoring, then you risk modifying (the suspect’s) behavior and losing them.”

Bryan Kohberger, 28, faces four counts of first-degree murder and one count of burglary in the early morning killings on Nov. 13. Kohberger, a doctoral student in criminology at nearby Washington State University in Pullman, was arrested at his parents’ home in Pennsylvania last week.

As the investigation continues to evolve and a motive remains unknown, here’s a recap of what authorities told the public before Kohberger’s arrest – and what they left out.
