Why I killed four students. You think my studies taught me how. You're wrong. They were a symptom of the obsession that was already there. My name is Brian Cobberger. This is a procedural account. The investigation found no personal connection between myself and the victims. The operation began with reconnaissance. Cell phone records placed my device in the vicinity of the King Road residence on at least 12 occasions prior to November 13th. These visits were concentrated in the late night and early morning hours, a methodical process of intelligence gathering. On the night of the event, I followed a specific protocol. At 2:47 a.m., my phone stopped reporting to the network, creating a 2-hour window of digital invisibility. Surveillance cameras captured my white Hyundai Elantre approaching the area. I made three initial passes by the residence, a final confirmation of the operational environment. At 4:04 a.m., I entered the area for the fourth and final time. I parked the vehicle and approached the house on foot. I gained entry through an unsecured sliding glass door on the second floor, which led to the kitchen. The first phase of the operation was complete.
