Eleven years after the brutal and mysterious murder of former Kabete MP George Muchai, his two bodyguards and driver, the Office of the Director of Public Prosecutions (DPP) closed its case against seven suspects.

Muchai was killed on February 6, 2015, within Nairobi's Central Business District, alongside his two bodyguards-Samuel Kailikia and Samuel Matanta, and his driver, Stephen Wambugu.  The prosecution wrapped up its case after presenting more than 37 witnesses in the murder trial.  Trial High Court Judge Kanyi Kimondo, however, directed all parties to file and serve their final submissions ahead of setting a judgment date.  He scheduled a meeting for June 24 to confirm compliance The seven accused, Eric Isabwa alias Chairman, Raphael Kimani alias Kim Butcher, Mustapha Kimani alias Musto, Stephen Astiva alias Chokore, Jane Wanjiru alias Shiro, Margaret Njeri, and Simon Wambugu, denied the murder charge.  On February 19, 2024, one of the key witnesses, Assistant Superintendent of Police Stephen Mwangi, unveiled what he described as an extensive web of communication among the accused before and after the murder.

In gripping testimony, Mwangi, who is also part of the investigating officers in the case, revealed that the accused had been in frequent contact, some exchanging over 150 phone calls in the critical days leading up to and following Muchai's assassination.

Mwangi, the prosecution's thirty-seventh witness, presented a detailed communication analysis matrix before Justice Kimondo, showing the pattern of calls exchanged among the accused from February 1 to February 10, 2015.
