The first major wagon train to the northwest departs from Elm Grove, Missouri, on the Oregon Trail.

Although U.S. sovereignty over the Oregon Territory was not clearly established until 1846, American fur trappers and missionary groups had been living in the region for decades, to say nothing of the Native Americans who had settled the land centuries earlier. Dozens of books and lectures proclaimed Oregon’s agricultural potential, piquing the interest of white American farmers. The first overland migrants to Oregon, intending primarily to farm, came in 1841 when a small band of 70 pioneers left Independence, Missouri. They followed a route blazed by fur traders, which took them west along the Platte River through the Rocky Mountains via the easy South Pass in Wyoming and then northwest to the Columbia River. In the years to come, pioneers came to call the route the Oregon Trail.

In 1842, a slightly larger group of 100 pioneers made the 2,000-mile journey to Oregon. The next year, however, the number of emigrants skyrocketed to 1,000. The sudden increase was a product of a severe depression in the Midwest combined with a flood of propaganda from fur traders, missionaries, and government officials extolling the virtues of the land. Farmers dissatisfied with their prospects in Ohio, Illinois, Kentucky, and Tennessee, hoped to find better lives in the supposed paradise of Oregon.

On this day in 1843, some 1,000 men, women, and children climbed aboard their wagons and steered their horses west out of the small town of Elm Grove, Missouri. The train comprised more than 100 wagons with a herd of 5,000 oxen and cattle trailing behind. Dr. Elijah White, a Presbyterian missionary who had made the trip the year before, served as a guide.

On May 22, 1981, police staking out a bridge over the Chattahoochee River near Atlanta, Georgia, hear a loud splash, and begin chasing Wayne Williams as he attempts to drive away in a station wagon. After questioning him about his involvement in the unprecedented string of child murders in Atlanta over the two previous years, Williams was released. He was arrested one month later, on June 21, 1981.

In a spree that began in July 1979, 29 Black children and young men disappeared or were killed in the Atlanta area. The only clue detectives had to go on was that many of the bodies had the same rare yellow-green nylon fiber on them, leading investigators to believe that all of the killings were connected.

As they desperately searched for the manufacturer of the fiber, a newspaper reported on the significance of the fiber evidence. Fearing that he was on the verge of being discovered, the killer then began dumping the bodies of his victims in the Chattahoochee River. This, in turn, inspired the police surveillance that ensnared Williams on May 22.

The rare fiber was eventually identified as a yarn that was sold to a Georgia carpet company, West Point Pepperell, which used it to make a line called Luxaire. The color of the fibers found on the bodies, including Nathaniel Cater, matched Luxaire English Olive; this was the type of carpet found in Williams’ home.

Experts estimated that one in approximately 8,000 Atlanta area homes contained Luxaire English Olive carpet. Prosecutors used this probability, along with fiber and hair evidence from Williams’ car and dog, to establish the fact that it was an extremely small chance that anyone other than Williams could be the killer. Adding to the already damning evidence against him, the killings immediately stopped after Williams was arrested.

On February 27, 1982, the jury found Wayne Williams guilty of the murders of Cater and Jimmy Ray Payne, and he was sentenced to life in prison. After the verdict, the Atlanta police department closed 22 other cases, but Williams was never tried, or charged, for those crimes.
