In 2006, the then MP, Mirugi Kariuki was killed in a plane crash in Marsabit on his way to a peace meeting. The crash also killed five other members of parliament. The ensuing by-election was contested and won by his son, William Kariuki Mirugi of the Narc-Kenya party. At the age of 27, Hon. William Kariuki Mirugi became one of the youngest members of parliament to represent Nakuru Town Constituency. He was however defeated by Lee Kinyanjui during the 2007 general elections beating his close rival Pastor Mike Brawan. The 2007 post-election violence also took a toll on the town, with dozens of buildings burnt to the ground by various factions.
