On the evening of November 11, 1874, German-immigrant Frederick Myers and his companion, William Murray, robbed and shot German immigrant Gotthard Wahl in a remote area north of Pittsburgh. Like Frecke and Marschall before them, the companions who had reportedly come to Pittsburgh only days earlier, made their livings through crime. Like Foerster, Wahl, a father of seven, was chosen because he was traveling alone, on an isolated road near Perrysville, and appeared to be a man of some means.
Murray, the leader of the two, fired the fatal shot. Wahl died the next day. After returning to their Third Avenue boardinghouse, an employee there who had heard of the killing became suspicious of their conduct and alerted authorities.
They were arrested on November 14.
Murray and Myers were convicted in separate trials in March 1875, and sentenced to death. Though there was some surprise that Myers was convicted of first-degree murder despite his secondary role in the case, their convictions were sustained on appeal (Myers and Murray v. Commonwealth, 79 Pa. 308, 1875).
William Murray and Frederick Myers were executed on January 6, 1876, before a reported crowd of 500 people, said to have been the largest crowd ever to see an execution inside the jail. Murray is reported to have suffered a slow and lingering death twenty minutes after the trap was sprung.
