His correct name is Durial321. It was June 6-7, 2006 on World 111 but If I remember correctly, he was the person who caused the "Falador Massacre", where he was able to attack people outside of the Wilderness, due to a bug with the Construction skill, and since he was at the house party of one of the first people to reach 99 Construction I believe (I think it was "Cursed You"'s), there were TONS of people there with their most expensive items to prove their wealth. There were 20 or so Player Mods there yelling out to everyone to bank their items, but it just so HAPPENED that Durial had the Ancient Magick spellbook and the appropriate runes to cast Ice Barrage. I'm pretty sure there is a video of it somewhere, taken by a person on his Ranging pure. Edit: You can find it on YouTube simply by searching his name.
