A postmortem examination revealed that Maryanne Wangari, a Bomet University student, was strangled to death.
Dr Weldon Kirui, Medical Superintendent at Longisa Referral Hospital, oversaw the postmortem examination following the death of the 22-year-old student.
He said they had also taken samples from her genitals for further tests.
“The findings indicate that the student died of strangulation and there were also other findings from the genitalia where lacerations were widespread. There were no other injuries found in the body,” Dr Kirui told journalists on Tuesday evening.
The body of the fourth-year communications student was found floating in Nyangores River on the outskirts of Bomet town on Monday, April 10 after she went missing on Tuesday last week.
Bomet Central deputy police boss Bashir Ali said four male students and a lady are being questioned over the incident.
“Our experts are analysing phone data in efforts to trace the last steps of the deceased,” Bashir added.
