Mega Edition: A Former Prosecutor And Resident At 1122 Discuss The Floorplan (8/6/26)

Former Idaho attorney general and prosecutor Dave Leroy believed the killer likely entered and escaped through a rear entrance on the upper side of the King Road residence. Because the house had been built against a hill, that entrance provided relatively direct access to the second and third floors, where Ethan Chapin, Xana Kernodle, Madison Mogen and Kaylee Goncalves were killed. Leroy suggested that this route could have allowed the attacker to reach the victims without moving through the lowest level of the house, potentially explaining why the surviving roommates downstairs were not physically harmed. However, he acknowledged that his reconstruction had been speculative and that investigators possessed far more information about the killer’s movements.

Former tenant Cole Alteneder said the residence had been old and creaky, with footsteps and movement often audible across its different floors. He explained that the home’s unusual multilevel design, staircases and wooden flooring made it difficult for someone to move around completely unnoticed, while its history as a popular gathering place meant that many University of Idaho students were familiar with the property’s layout and entrances. His account raised additional questions about what noises might have been heard during the killings, although it did not establish how loud the attack had been, what the surviving roommates actually heard or whether any sounds would have been immediately recognized as evidence of a violent crime.
