Born and raised in Goliad County, Brack Cornett was a member of the Bill Whitley gang. With Whitley and others, Cornett robbed banks and trains in southwest Texas. The gang robbed the bank at Cisco, Texas, taking $25,000. A few days later the gang took $20,000 from the express car on the IG&N train in Travis County. A posse was waiting for them at Harwood, the gang giving up their attempt. In Wilson County, the gang was finally trapped by U.S. Marshals on September 25, 1888. The gang opted to shoot it out with the law, Whitley being killed. Cornett took off across the plains where he was killed in a shoot-out with Deputy Sheriff Alfred Allee.
