One of three people convicted of planning the Garissa University terror attack five years ago has been found dead in his cell. 

Rashid Charles Mberesero was found dead at Kamiti Maximum Prison where he was serving a life sentence.

“He committed suicide on Friday at 1520hours inside his cell using a blanket that he used to hang himself with from the grills. He was alone but the matter is under investigation. The body has been taken to the City Mortuary awaiting autopsy,” said Kennedy Aluda, Prisons Spokesman.

Aluda told Citizen Digital on Sunday that the matter would be handled by the embassy since the dead convict was a Tanzanian.

In April 2, 2015 terrorists struck at Garissa University killing 156 people.

Mberesero, Hassan Edin Hassan and Mohammed Abdi Abdikar were convicted for being members of al Shabaab terror group, committing a terrorist act and conspiracy to commit terrorism.

In his ruling, Magistrate Francis Andayi said the three terror suspects were in communication with the attackers and knew of the terror plot.

Andayi indicated that the attack was conducted to coerce the Kenya government into removing Kenya Defense Forces (KDF) from Somalia.

According to the court, Mberesero led the attackers to the university and was unable to explain his presence in the hostels. 

More than 22 witnesses testified in the case that got the three convicted, including Garissa University students.
