At least 14 people were Friday morning when a lorry rammed onto a matatu at Migaa area, Molo on the Nakuru-Eldoret Highway.
Police said all on board the Kitale Shuttle matatu died in the 3 am incident on March 14.
Migaa area is regarded a black spot.
No one survived the accident. 12 of the victims were from the matatu who included the driver and two from the lorry. The lorry was carrying coffee seeds.
The victims included nine male, four females and a child, police spokesman Michael Muchiri said.
He said preliminary findings show the lorry’s driver lost its control before it rammed onto the matatu and dragging it for a while fatally trapping the passengers on board.
The bodies were moved to the mortuary pending autopsy and investigations.

Police said they are launching a campaign to address the menace.
Fatal traffic accidents have been on the rise in the country amid a campaign to address the trend.
Police have teamed up with government agencies in the campaign.
More than 4000 people are killed annually in accidents in the country. Thousands of others are left with injuries that leave a trail of negative impact on families.

Also, overtaking improperly and failing to keep the proper lane, resulting in head-on collisions, are mentioned as causes.
