Chasing Lincoln's Killer Practice Test 2026 – Complete Exam Prep

The key idea is that not everyone charged in the aftermath of the assassination was actually part of the central plot. Edman Spangler, a Ford’s Theatre carpenter, was accused of conspiracy and briefly imprisoned, but evidence and historical understanding suggest he did not know about or participate in the plan to kill Lincoln. He served a short time and was released, while others tied more directly to the plot faced harsher outcomes. So, he’s the one who was found guilty despite not being truly involved in the core crime, making him the best answer.
