Security consultant Peter Ndwiga Njiru's decision to park his Toyota Probox KDB 506 U at a bus stop aided police and his family to act quickly in investigating his cold-blooded murder.
His wife, Wambui Ndwiga recounted to Citizen TV how it was very unusual for her husband to sleep out.
That set alarm bells for her and the next morning, on Wednesday she rushed to the Juja Police Station and reported Peter Ndwiga as a missing person.
The only clue to Ndwiga's last known locations was discovered by police after his car was towed to Juja Police Station, he had parked it along the highway when he met up with rogue cop Caroline Kangogo for a quick drink at 4 pm on Monday, July 5.
But he never made it back to the car or home.
This fact, aided the police and his family to discover that Ndwiga was Caroline's second victim.
A grief-stricken wife said, "My husband was not one to sleep outside ever. That night when he did not make it back home I knew something was amiss."
Ndwiga's lifeless body was found lying in a bed at Hotel Dedamax, in a pool of blood oozing from a single gunshot wound on his head.
"The manner in which he died is a shock, a huge shock," the wife said.
A post-mortem was conducted at General Kago morgue in Thika, Kiambu County revealed that Ndwiga had a single bullet wound that caused a fatal brain injury.
Doctor John Mathaiya, the consultant pathologist, revealed that the bullet entered the left region of the head around the ear and exited on the right side. The bullet mutilated parts of Ndwiga’s brain among them cerebrum and the brain stem.
