A middle-aged man was on Saturday morning found dead inside a guest house in Kitui.
The incident was confirmed by Kitui Central Sub County Director of Criminal Investigations Singi Nzyoka.
According to Nzyoka, the departed had traveled from Western and was in the company of two other men.
Phone records showed that the deceased was on his way to Mbitini for an appointment with a witchdoctor.
Speaking to Musyi FM, Singi said the deceased is suspected to have overdosed on a sexual enhancement pill.
He did, however, note that an autopsy will reveal the cause of death and help investigators close the matter.
The body of the deceased has since been moved to the Kitui Level Four Hospital Mortuary.
