Seven more bodies have been retrieved from River Yala in western Kenya near the spot where a dozen others have been discovered over the past two years.
The unclaimed bodies were retrieved from the river in the last two months, according to a police report seen by officials at Yala sub-county mortuary.
The bodies have not been identified as they await autopsy.
Mortuary officials say three bodies were retrieved by divers in September and the other four were discovered by residents along the river.
The latest discovery increases the tally of bodies retrieved from the river to more than 30 since January.
Human rights activists say residents in the area are living in fear over the discovery of unidentified bodies from the river.
