The atmosphere was tense, with visible concern among those gathered as they shared details surrounding his unexplained disappearance.
According to the lawyer, the family officially filed a missing person report at Karen Police Station after efforts to reach Nyamondi-Tuju proved unsuccessful.
What has raised alarm is the fact that all his mobile phones have been switched off since Saturday night, something described as highly unusual given his routine and active communication habits.
The situation became more worrying when Nyamondi-Tuju failed to appear for a scheduled evening radio interview.
Those who know him say he is known for keeping time and honoring his commitments, making his absence even more troubling.
Further deepening the mystery, his car was later found abandoned along Miotoni Lane in Karen.
The vehicle has since been towed to Karen Police Station, where it is being held as part of the ongoing investigation.
Detectives from the Directorate of Criminal Investigations have taken over the case and are now working to piece together the events leading up to his disappearance.
Family members have expressed fear and frustration, urging authorities to act swiftly and thoroughly.
They described Nyamondi-Tuju as a responsible individual with no known conflicts that would explain his sudden disappearance.
Friends who spoke at the press briefing echoed similar sentiments, saying his silence and absence are completely out of character.
As the investigation continues, questions remain unanswered. What happened between the time he was last seen and when his car was discovered? Why were his phones switched off? And most importantly, where is he?
