Michael Shelby — former U.S. Attorney for the Southern District of Texas from 2001-2005 and more recently a partner at Houston’s Fulbright & Jaworski (previous posts here and here) — died at his home in northwest Houston on Tuesday from what authorities described as a self-inflicted gunshot wound. Shelby, who was 47, had been suffering from cancer that had rendered him unable to work in recent weeks. The Chronicle story on Shelby’s life is here.
