“Study my brain. I’m sorry,” Tisch quoted Tamura as having written in the note. The commissioner noted that Tamura had fatally shot himself in the chest.

Didn’t shoot himself in the head to preserve the brain. Reminds me of the “Texas Tower Shooter” Charles Whitman.

In his note, Whitman went on to request an autopsy be performed on his remains after he was dead to determine if there had been a biological cause for his actions and for his continuing and increasingly intense headaches.

During the autopsy, Dr. Chenar reported that he discovered a pecan-sized brain tumor, above the red nucleus, in the white matter below the gray center thalamus, which he identified as an astrocytoma with slight necrosis.

I’ve heard a neuroscientist talk about this and conclude that this tumor could very well have been the cause for his behavior.
