The Moi Girls School, Nairobi rape incident mystery has taken a new twist after the DNA analysis results cleared male teachers and workers in the case.
Experts carrying out the DNA tests have concluded that the samples collected from male staff in the institution did not match those taken from the student who reported she was defiled.
According to investigators, the test is important in determining sexual violence cases as it allows forensic experts to compare the profile of a suspect against the evidence of body fluids found on the victim.
Male workers including teachers underwent a mandatory DNA test in connection with the rape of a student at the institution after it was suspected that the culprit was possiby an insider.
DNA test are crucial in placing a suspect either at the scene of the crime or absolving him/her since the results of the tests carry more weight in court than verbal submissions.
Previous reports from independent investigations have raised concern that a crop of lesbian students at the school might have molested their colleagues.
The Kenya Union of Post Primary Education Teachers (KUPPET) had also pointed out inconsistencies in the claims after carrying out an independent inquest on the circumstances surrounding the assault.
In concluding the probe, it was difficult for the union to picture a man being involved in the alleged rape case that saw the school principal Jael Muriithi opt for early retirement.
Both KUPPET and the school's own investigations point to a possibility of lesbian students having molested their colleague.
"If you enter the school you have to pass two dormitories before getting to Elgon, the hostel where the girl was. Why would a rapist pass two hostels and specifically go to Elgon?" an official queried insisting on anonymity.
According to the officer, the student at the center of the claims woke up in panic upon realizing she spent the night on another girl’s bed. The official refuted claims that security cameras at the school were faulty, adding that footage could not show a stranger accessing the dormitory area as claimed by the students.
