Two Indian tourists and their local driver disappeared in the Kenyan capital, Nairobi, on a July night.
More than two months after the incident, nine policemen have been arrested in connection with the case, which India says it is "closely watching".
In one of his last social media posts before he disappeared, Zulfiqar Ahmad Khan shared a video of a roaring lion in Kenya's Maasai Mara game reserve where he had been holidaying.
The 48-year-old Indian media marketing professional had last worked as the chief operating officer of Balaji Telefilms, a Mumbai-based TV company.
Mr Khan told friends he would return home on 24 July and that he also wanted to come back to Kenya to witness the annual "Great Migration"
The second Indian was Mohammad Zaid Sami Kidwai, 36, who had also come to Nairobi on a tourist visa, hailed from the northern Indian city of Lucknow and lived in Dubai
The two Indians were in Kenya to help the election campaign of William Ruto, a charismatic 55-year-old politician who was sworn in as the country's fifth president in September
Nearly three months later, Kenyan police claimed to have made headway: nine policemen have been arrested since 21 October in connection with an incident of kidnapping and murder of the three men.
The policemen were part of an elite squad called Special Services Unit that was disbanded by President Ruto last week for allegedly carrying out extrajudicial killings of suspects over several years
