The focus has shifted to the ballistic analysis of two guns belonging to the nominated MP David Sankok following the death of his son at their home in Narok County.
Police took his shotgun and Ceska pistol found in the house for analysis and examination.
They also collected shells believed to have been discharged from the shotgun, which now they believe Memusi Sankok, 15, used to blow up his head.
The detectives at the Directorate of Criminal Investigations want to understand how Memusi could handle the shotgun to shoot himself in the chin.
An autopsy conducted on the body revealed the cause of Memusi’s death was a gunshot to the chin that exited through the head.
Detectives will be seeking to establish whether the bullet head recovered at the scene was shot from the firearm.
They will also be keen to match the fingerprints on the trigger of the shotgun to the deceased.
“Unless it was redesigned, it is hard for a 15-year-old boy to operate the shotgun. It has a long handle,” said an officer aware of the probe.
Narok County DCI boss Mwenda Ethaiba said the guns are at the DCI headquarters, and experts will report on their usage.
He said they had confirmed Sankok is a licensed firearm holder.
“The weapons were legally held by the MP. They are now under examination,” he said.
Ethaiba said they have so far recorded statements from 10 people, including Sankok, his wife and daughter, as well as workers at his hotel who were at his home at the time of the incident.
It is alleged that the legislator differed with the son over his delay to report back to school before a verbal altercation ensued between them.
His son, who was angry at the time, is suspected to have gone for a shotgun in a safe and used it to blow up his head.
Police are planning to recommend that Sankok be charged with negligence in handling his firearm.
