3:50 in the morning in a church. A figure was standing at the end of the hallway. Full tactical gear, helmet, face shield down. He start walking. For 30 minutes he walked through the church breaking open doors one by [music] one slowly methodically. The vest says police. He was not police. Analyst study [music] the walk. Some say it doesn't match her man. The helmet hides everything. The face is never visible. 4:20 a.m. Missy Beavers [music] arrive to set up her fitness class. She walks into the church. Someone is already inside. 5:00 a.m. Her students [music] find her body. Puncture wounds to the head and chest. The same tool that broke the doors. [music] 30 minutes of footage, eight camera angles. Nobody knows who they are. 10 years, one church, one hammer, [music] 30 minutes of a killer on camera, and a face that was never visible. Who walked through that church?
