A dead drunk Thomas Haldeman went to sleep under a tree near Nopal, Texas on December 17, 1872. He never woke up. Brown Bowen, brother-in-law of John Wesley Hardin, put a bullet in Haldeman’s head, supposedly because the victim was an informer for the state police.
Bowen was arrested but Hardin engineered a jail break. He was recaptured in Florida four years later and convicted in the Haldeman killing. Bowen accused Hardin of the murder, but an eyewitness said Bowen pulled the trigger. Brown Bowen died on the gallows on May 18, 1879.
