What happened April 1986 AD

In April, shortly after the new date (July 2) was announced, Bundy finally confessed to Hagmaier and Nelson what they believed was the full range of his depredations, including details of what he did to some of his victims after their deaths. He told them that he revisited Taylor Mountain, Issaquah, and other secondary crime scenes, often several times, to lie with his victims and perform sexual acts with their decomposing bodies until putrefaction forced him to stop. In some cases, he drove for several hours each way and remained the entire night. In Utah, he applied makeup to Melissa Smith's lifeless face, and he repeatedly washed Laura Aime's hair. "If you've got time," he told Hagmaier, "they can be anything you want them to be." He decapitated approximately 12 of his victims with a hacksaw and kept at least one group of severed heads—probably the four later found on Taylor Mountain (Rancourt, Parks, Ball, and Healy)—in his apartment for a period of time before disposing of them.

In April 1986 the Chernobyl disaster occurred.

Accidents in nuclear power plants include the Chernobyl disaster in the Soviet Union in 1986. It is considered the worst nuclear disaster in history and was caused by one of only two nuclear energy accidents rated at seven the maximum severity on the International Nuclear Event Scale.

A commission was established later in the day to investigate the accident. It was headed by Valery Legasov, First Deputy Director of the Kurchatov Institute of Atomic Energy, and included leading nuclear specialist Evgeny Velikhov, hydro-meteorologist Yuri Izrael, radiologist Leonid Ilyin, and others. They flew to Boryspil International Airport and arrived at the power plant on the evening of 26 April.

The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 nuclear reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR. It is considered the worst nuclear disaster in history and is one of only two nuclear energy disasters rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima Daiichi nuclear disaster in Japan.

On the morning of 28 April, workers at the Forsmark Nuclear Power Plant (approximately 1,100 km (680 mi) from the Chernobyl site) were found to have radioactive particles on their clothes.
