On this day, April 19, in 1995, in an eerie coincidence, a white supremacist who once plotted to blow up the Alfred P. Murrah Federal Building in Oklahoma City was executed on the same day that Timothy McVeigh successfully bombed the federal building.

Richard Wayne Snell, 64, was put to death in Arkansas for killing a black state trooper and a pawnshop owner he believed was Jewish.

In 1983, Snell plotted to remotely launch rockets from a van parked in front of the Murrah building.

Snell and McVeigh ran in the same circles. On the day of his execution, Snell watched televised reports of the Oklahoma City bombing. The attack killed 168 people and injured 800.

McVeigh never mentioned Snell and said the atttack was in response to the federal government's handling of the attack on the Branch Davidian compound in Waco, Texas.
