Arthur Tillman and Mandy Stephens
Briefly, the facts of the case were as follows: Tillman, as he freely admitted at trial, was having regular sexual relations with Mandy and she turned up pregnant. She had also gotten pregnant and miscarried three years earlier, and Tillman had been one of several young men who had had sex with her prior to her first pregnancy. This time she was pressing Tillman to marry her, but he had another girlfriend and did not want to marry Mandy. The couple, though, were seen together on the day Mandy disappeared. Confronted, Tillman claimed not to know where Mandy was and then left town. A few days later he came back and was seen looking into an abandoned well on a neighbor's property adjoining the Tillman family farm. The next day, Mandy's body was found at the bottom of the same well, with a rock tied to her body with telephone wire. By the time the body was retrieved, Tillman had again skpped town but was tracked down at Fort Smith a couple of days later and brought back to face murder charges.
At his trial, it was revealed that telephone wire exactly matching that used on Mandy went missing from a general store in the Tillman neighborhood on the same day Mandy went missing and that Tillman was seen by witnesses in the vicinity of the store. Mandy had been killed with shots from a .22 rifle, and testimony further revealed that Tillman's father had given away a .22 rifle a day or two after Mandy went missing. A doctor testified that on the day before Mandy's disappearance, young Tillman had come to him seeking a potion or medicine that would abort her pregnancy but that he told Arthur he had no such medicine. The defense, of course, attempted to explain all these circumstances as mere coincidence. The defense also tried to suggest that Mandy's father had killed his own daughter or that perhaps Tillman's father had done the deed. However, the prosecution in turn rebutted the defense's rebuttal.
Tillman's first trial ended in a hung jury, with eleven voting for conviction and one for acquittal. He was retried, convicted with a unanimous verdict, and hanged in July 1914.
This, of course, is just a bare-bones accounting of the case. For full details, you need to read the book. By the way, I'm having a book signing for Desperadoes at Half Price Books of the Ozarks on the Plaza Shopping Center in Springfield on Saturday, November 19, from 1-3 p.m.
