Jack "Red Jack" Almer, aka: Jack Averill - (18??-1883) - Almer was the leader of the Red Jack Gang who preyed on Arizona stagecoaches during the early 1880s, particularly along the San Pedro River. When the gang held up a Globe, Arizona stage on August 10, 1883, the Wells Fargo guard insisted that they were not carrying any gold. However, a "female" passenger jumped from the stage, insisting the guard was a liar. Dressed in women's clothing, it was Almer.

When the guard went for his gun, Red Jack shot him dead and the gang took of with nearly $3,000 in bold and cash. In no time, posses were formed and Sheriff Bob Paul was intent on catching the gang. One by one he tracked down every member of the gang and found Almer hiding near Willcox, Arizona on October 4, 1883. in the ensuing gunfight, “Red Jack” was shot down by Sheriff Bob and his posse when he tried to battle his way out.
