Death
On 15 May 2011, Wanjiru died from a fall off a balcony at his home in Nyahururu. Wanjiru appeared to have suffered internal injuries after the fall and was confirmed dead by doctors at a nearby hospital after attempts to revive him failed.
Police said Wanjiru's wife, Triza Njeri, had come home to find him in bed with another woman. She locked the couple in the bedroom and ran outside. Wanjiru then died after falling from the balcony. Police are unsure if Wanjiru intended suicide or jumped out of rage, and are investigating the circumstances related to Njeri and his female companion that led to his death.
In May 2017, while testifying during an inquest into Wanjiru's death, his mother Hannah Wanjiru said at the Milimani law court that she believes her son was murdered.[
His mother claimed at an inquest into his death that her son was murdered by six men who had conspired with his wife Trizah Njeri. During the inquest at the Milimani court that sought to establish whether Wanjiru was murdered or jumped to his death, a former chief government pathologist said he was convinced that Wanjiru was hit by a blunt object after he had jumped from the balcony of his home, landing on his legs, or possibly he was pushed then struck.][
