Investigators believe the vehicle was used by individuals who trailed the Kasipul lawmaker shortly before the fatal shooting that shocked the nation.
The officer has since appeared before the court and testified as a State witness in the murder trial.
During his testimony, Haikal explained the circumstances under which his vehicle may have been used and how it became part of the investigation.
His statement is considered important as prosecutors try to piece together the events that led to the killing of the legislator.
The murder of Were sent shockwaves across the country and raised serious questions about security and political violence.
Were was known as an outspoken leader who represented the people of Kasipul in Parliament.
His sudden death not only left his constituents in mourning but also triggered calls for thorough investigations to ensure those responsible are brought to justice.
According to investigators, the suspects are believed to have used the white Toyota Mark II to follow the legislator while he was moving within the city.
Detectives told the court that the car was seen near locations where the MP had passed shortly before the shooting occurred.
Authorities suspect it played a key role in monitoring his movements before the attackers struck.
However, police have clarified that the vehicle’s ownership does not necessarily mean the officer was involved in the crime.
Instead, Haikal’s testimony is meant to help investigators understand how the car may have been accessed or used by the suspects.
Prosecutors say the officer has been cooperating with authorities since the investigation began.
During the court session, Haikal told the court that he was aware that his vehicle had been mentioned in the investigation.
He explained that once he was contacted by investigators, he provided all the information required to assist with the case.
The court heard that the officer is helping the prosecution establish a clearer timeline of events leading to the murder.
Detectives continue to rely on witness statements, surveillance footage, and forensic evidence as they work to uncover the full details behind the killing.
The case has attracted significant public attention, with many Kenyans following the proceedings closely in the hope that justice will be served.
