TMZ spoke with retired FBI agent Jennifer Coffindaffer, who has closely followed the Kohberger case and frequently serves as a media analyst. She has now shared with TMZ her disturbing theory regarding Kohberger’s motive on the night of the murders.

Coffindaffer claims Kohberger broke into the Moscow, Idaho home in November 2022 with the intention of assaulting Mogen in her third-floor bedroom. However, she says his plan unraveled when he entered the room and discovered that Mogen was not alone — Goncalves, her roommate, was sleeping beside her.

According to Coffindaffer, Mogen was Kohberger’s primary target, evidenced by the fact that he went directly to her room. Seeing Goncalves there allegedly enraged him, as her presence prevented him from carrying out his intended assault.
