The Dutch embassy in Nairobi reported Cohen missing after his family approached Dutch police, saying they could not reach him on his mobile phone and it was unusual for him to be out of touch for long.
Investigators say he met at least two women over lunch at the club on July 20 from around 2pm to 4pm. The two women told police during questioning that the 71-year-old golf lover left the club and they did not know his whereabouts.
Police questioned several people, including his wife and workers.
A day before his body was found, a charge sheet produced in court indicating that Sarah Wairimu would be charged with the murder of Tob Chichou Cohen on the night of July 19 or July 20, 2019 at dawn.
Wairimu, however, was not required to plead before Milimani High Court Judge Charles Kariuki. Instead Justice Kariuki directed the prosecution to conduct a mental health assessment on Wairimu before charging her with murder.
