Sam Bass (outlaw) - Wikipedia

On July 21, 1878, Sam Bass, American Old West train robber and outlaw, died at age 27. Died on his birthday. From the article:

"Bass was able to elude the Texas Rangers until a member of his gang, Jim Murphy, turned informant. Mr. Murphy's father, who was very ill at the time, had been taken into custody and held for questioning. He was not allowed to be seen by a doctor and was prevented from receiving medical treatment, which caused his condition to rapidly worsen. Lawmen sent a message to Murphy informing him that they had his father in custody, and that if Murphy did not agree to meet with them, they would continue to withhold medical treatment from the father. Knowing how sick his father was, Murphy agreed to the meeting. There, he reluctantly agreed to turn informant. John B. Jones was subsequently notified of Bass's movements and set up an ambush at Round Rock, Texas, where Bass and the gang planned to rob the Williamson County Bank."
