On this day, April 16, in 1997, Houston’s top bookie, Robert Angleton, found his socialite wife shot to death at the couple’s upscale home.

It appeared to friends that Doris Angleton might have been killed by her husband’s underworld rivals, but then Robert’s brother Roger was found in Las Vegas with typewritten notes about the murder and a tape of Roger discussing how the murder went down. Police believed Bob was the other voice on the tape.
