The friends who were with him at that time said he was in good health and had not complained of any sickness.
He was rushed to Thika Nursing Home where he was pronounced dead while being attended to. The body was later moved to the Lee Funeral Home.
Thuo was one of the original owners of City Hoppa public service vehicles. He was also once the managing director of the defunct Kenya Bus Service PSVs and later Stagecoach buses.
He was first elected as an MP in the 2007 elections on a Party of National Unity (PNU) ticket to represent Juja Constituency.
He also served as the then Government Chief Whip.
In April 2010 he lost the parliamentary seat after a court nullified the 2007 election results of Juja Constituency citing irregularities.
A by-election was subsequently held on September 20, 2010, but Thuo was left third after William Kabogo (NARC-Kenya) and Alice Wambui of Kenya National Congress.
Many have mourned his death.
