Three of the four men who were shot dead in unclear circumstances in Buruburu estate, Nairobi have been identified.
They all come from Gitaru, Kiambu county, police said.
A fourth man is yet to be identified.
On Wednesday, family and friends of the three men gathered at the City Mortuary where a post mortem examination was conducted on the bodies.
Pathologist Dr Peter Ndegwa , who conducted the examination on the three bodies concluded they all died of excessive bleeding as a result of multiple gunshot wounds.
Among the three men who have so far been identified include Brian Mwangi Kariuki 24, Benson Mwangi Kinyua 22, and Julius Mwangi aged 25.
Brian’s identity card was found in a car they were using when they were shot dead on December 24.
This alerted his relatives who rushed to the mortuary and identified him alongside two others.
Police say they do not know who shot the four.
A relative to Brian who is among those killed said the family is seeking justice for the death of their son.
The four men were shot dead by unknown people on Christmas Eve in Buruburu.
Their lifeless bodies were discovered inside and outside a car they were using.
Initial reports by Buruburu police said the four had suffered multiple gunshot wounds.
Police said they found three bodies outside a motor vehicle that was parked in the estate.
The fourth body was found inside a grey Suzuki Swift.
According to the police, daggers were found inside the vehicle.
One of the recovered daggers was found on the killed men while another weapon was found inside a car where the body of one of the men lay.
Officers who arrived at the scene at around 7 am, said they were informed of the bodies by a resident who claimed to have heard gunshots on Saturday night.
The residents who called the police said at around 3 am on Saturday, he heard gunshots from the direction of one of the shops located on the building where he lives.
The residents told police he thought that some residents were cracking fireworks ahead of the Christmas festivities.
Preliminary findings show three of the victims who were found outside the vehicle were sprayed with bullets while lying down on the ground.
