Sh8.5 million was raised by the police and Provincial Adminisration while MPs donated Sh6.6 million.
Commissioner of Police Mathew Iteere eulogised the officers as dedicated.
He said he had supervised Murimi and Oyugi at the GSU Training School where they were trained and Tonkei at the Presidential Escort Unit where he was the commandant and the deceased officer a security man.
“I knew Nancy as a dedicated pilot who also carried me and other officers to and from several other places while she served for 13 years as a pilot,” Iteere said.
The caskets bearing bodies of the officers were driven in four vans and paraded outside the Holy Family Basilica, where an interdenominational service was conducted.
All the four police officers will be buried this week.
