It’s beginning to look like the guy who walked into Bush Intercontinental Airport Thursday was indeed suicidal, thanks to evidence provided by a suicide note he left. He talks about a darkness inside him that he was fighting, and apparently losing. He reportedly tried to kidnap a woman with whom he was infatuated earlier in the week, then drove from Beaumont to Houston to end his life. In the final moments, DHS agents claim that he pointed his gun at an agent who fired in self defense, striking the suspect in the shoulder. However, reports also indicate that the shooter almost simultaneously put the gun to his own head and ended his life. The news outlets also indicate that he tried to get people to leave the area before he opened fire, indicating that he only wanted to kill himself and no one else.
