Rebecca Key (2450)

10/7/2004: County deputies were looking to serve an arrest warrant to Key's friend, the owner of the house, but upon spotting deputies Key barricaded herself inside and began collecting weapons. During an extended standoff members of a SWAT team cut off electricity to the house, and a police negotiator urged her "to appreciate the spiritual impact of suicide." She emerged, threatening officers with a weapon, and was shot to death.
