Kenyatta National Hospital (KNH) is once again in the spotlight following the brutal murder of a patient - a murder that came about five months after the macabre killing of Gilbert Kinyua in February.

Edward Maingi Ndegwa is the latest victim in a string of crimes that badly expose security lapses at the largest referral facility.  That a patient can be killed in broad daylight without anyone noticing is a cause of concern regarding patients' safety and level of security at KNH, which on any ordinary day, is a beehive of activities.

Many questions are being asked as to how a patient in the country's apex referral hospital and in a general ward could have his throat slit without anyone noticing.

Kinyua's case had gone cold.
