They include former Interior CS Fred Matiang'i, Ukur Yattani (Treasury), Eugene Wamalwa (Defence), Joe Mucheru (ICT) and former Interior PS Karanja Kibicho.
President Kenyatta had, last week, asked the former CSs to form a committee to help Magoha's family with funeral arrangements.
Magoha will be buried on February 11, 2023, in Yala, Gem Constituency, Siaya County.
