Police in Diani, Kwale county are investigating the mystery surrounding the death of a Buru Buru Girls High School teacher, who died on Sunday. Yesterday, detectives said they have launched probe into the death of Nelson Otsianda, who had booked himself into Gasimba Villas, alongside his colleagues. Msambweni police boss Fanuel Nasio told People Daily that Otsianda, 30, was found lying in the swimming pool, however, Amauchi\u2019s family has refuted the statement, alleging foul play in his death. \u201cWe have launched investigation into the matter. The deceased was found to have drowned in the pool,\u201d Nasio said. Police boss said they had received information from the hotel management that the deceased had been swimming before he met his death. \u201cThe report given to us is that there was a guest who was swimming at the pool but drowned. We are still investigating the matter,\u201d Nasio stated. The body was moved to Jocham Funeral Home in Mombasa. Otsianda\u2019s father, Cloud Amauchi, accused his son\u2019s four colleagues who were with him of having a hand in his death. \u201cThey were at the pool together with my son, so how come all the four could not help him? I appeal to the government that investigations be conducted and these teachers be held responsible,\u201d Amauchi said. He said the family\u2019s plea to the resort\u2019s management to avail the CCTV footage had been rejected. \u201cWhy has the management of the villas denied us access to the CCTV server? That means there is something fishy,\u201d he said. Shared post A post shared widely on social media claimed the teacher was killed before his body was thrown into the pool to create the impression that he had drowned. \u201cA Buru Buru Girls teacher went with colleagues to Mombasa and now he is dead. The hotel that had hosted them says he fell in a swimming pool while drunk. So the brother to the deceased demands for a CCTV footage, the hotel says it was not functional. He insists on accessing the main server. To his shock, he sees two men clobbering his brother and killing him then throws (sic) him to the swimming poll. What is the hotel hiding,\u201d reads the social media post.
