He had a nickname for every mood — Moses, Interstate, Palace, Gazava, Scorpio King, Bleau Barracuda. Online, he seemed to be screaming at people to pay attention. “Welcome To Greatness,” proclaimed a photo album on his Facebook page.

In reality, Mr. Brinsley’s short life was a series of disappointments.
