HUNTSVILLE, Tex. — Karl Eugene Chamberlain went to his neighbor’s apartment that night in Dallas under the pretense of borrowing sugar. He returned later, forced her into a bedroom, bound her hands and feet, raped her and then used a rifle to shoot and kill her. His victim, Felecia Prechtl, 29, was a single mother with a 5-year-old son.

Eleven years after he was convicted of capital murder, Mr. Chamberlain, 37, was strapped to a gurney in Texas’ execution chamber at the Walls Unit prison here and was asked by a warden if he had any last words. “Thank you for being here today to honor Felecia Prechtl, whom I didn’t even know,” he told her son, parents and brother on June 11, 2008. “I am so terribly sorry. I wish I could die more than once to tell you how sorry I am.”

His words did not die with him. Texas wrote them down, kept them and posted them on the Internet.

The state with the busiest death chamber in America publishes the final statements of the inmates it has executed on a prison agency Web site, a kind of public catalog of the rantings, apologies, prayers, claims of innocence and confessions of hundreds of men and women in the minutes before their deaths.

Charles Nealy asked to be buried not to the left of his father but to the right of his mother. Domingo Cantu Jr., who dragged a 94-year-old widow across the top of a chain-link fence, sexually assaulted her and then killed her, told his wife that he loved her and would be waiting for her on the other side.
