If you have not heard of Humphrey Mulindi Mathahana and Steve Ochieng Odiambo, then you need to use your Google search appropriately. These two are notorious fraudsters linked to a spate of gold -, diamond -, and minerals-related fraud. The DCI has, at a certain time, branded them dangerous.
For instance, the two are facing criminal-related charges before Milimani Magistrate Nyaguthi.
According to the charge sheet read in court, they jointly, on diverse dates between February 3, 2021, and March 5, 2021, at an unknown place within the Republic of Kenya, conspired to defraud Emily Silaton Mututua, a director of Milestone Gemstone Kenya Limited Company, of Tanzanite minerals measuring 687.283 carats valued at USD 203,436 equivalent to Sh 22,337,273 by falsely pretending that he would sell the said Tanzanite minerals to Dubai, knowing it was untrue. They convinced the said businessman that they were in a position to help him fix the said business.
The court also heard that the two, Humphrey Mulindi Mathahana and Steve Ochieng Odiambo, obtained goods by false pretences contrary to the law.

According to the court papers, they committed the offence on February 5, 2021, at Ministry of Mining offices within Nairobi County, obtaining Tanzanite minerals measuring 456.8 carats valued at USD 147,553, equivalent to Sh 16,201,319, from Emily SILATON MUTUTUA, a director of Milestone Gemstone Kenya Limited Company, by falsely pretending that he would sell the said Tanzanite minerals measuring 456.8 carats to Dubai, knowing it was untrue.
For instance, Humphrey Mulindi Mathahana and Steve Ochieng Odiambo committed the offence on March 5, 2021, at ministry offices within Nairobi County, where they obtained Tanzanite minerals measuring 230,483 carats valued at USD 71,883, equivalent to Sh 7,892,753, from Emily Silaton Mututua, a director of Milestone Gemstone Kenya Limited Company, by falsely pretending that he would sell the said Tanzanite minerals measuring 230,483 carats to Dubai, knowing it was untrue.
