The four University of Idaho students – Kaylee Goncalves (21), Madison Moggin (21), Zana Kernodle (21), and Ethan Chapin (20) – were found stabbed to death in a home near the campus in Moscow, Idaho. In November. 13, 2022.

More than a month and a half later, police arrested and charged criminology student Brian Christopher Kuhberger with the murders.

But Kohberger denies his guilt. The reason for the murder of the four students remains a mystery, but in a new book, journalist Howard Bloom provides new information and launches his own theories.

Among them is that Kohberger was initially looking for Mugen.

– I think Maddie was his target, says Bloom in an interview with Letters of News.

He explains that the suspect must have passed two other bedroom doors and headed straight toward Mugen's room when he entered the house.

-If he had just wanted to kill anyone, it would have been natural and instinctive for him to go to one of those doors. Instead, he goes up that narrow staircase and straight into Maddie's room, Bloom explains.

The book also provides new information about what the other two roommates were doing at the time of the murder.

The two were in the house when the murder occurred, but police did not suspect either of them. He wrote in the book that his sources say the two used a mobile phone to communicate during and after the murders.

– According to testimony presented to the grand jury, the girls communicated and texted each other not only after the murders occurred, but at some point during the murders, Bloom told ABC.

More than a year later, Kohberger remains in custody. No trial date has been set.
