Simiyu was hiding beneath the staircase where he witnessed the callous murder of his fellow students. Tana River Hostel was the first to be raided by the militants. He said that when the terrorists ran out of bullets they resorted to butchering some of their victims with knives.
Simiyu credits his survival to God:
“They hurled grenades at any point they suspected there were people below the stairs but God kept protecting us as the grenades hit the wall and fell.,"
He went to say that more students would have survived had the Recce squad arrived earlier.
The attack, according to one student, lasted for three hours without any intervention.
