William W. McKee
On April 23, 1926, information was received that a liquor pack train had left Nogales, Sonora, Mexico, for the United States and on that date would be at or near the Alhambre Ranch about 40 miles southwest of Tucson, Arizona. Near the ranch, officers of the Border Patrol saw such a pack train and in an attempt to capture it, Patrol Inspector William W. McKee was shot and killed at the wheel of a patrol car. The smugglers fired from ambush while being pursued by Inspector McKee. The smuggler responsible for killing Inspector McKee was later convicted of first degree murder.
