Three Garissa University attack convicts, were on Wednesday sentenced for abetting the attack on the Institution in 2015, that left 147 people dead.
Nairobi Chief Magistrate Francis Andayi handed Mohamed Ali Abdikar and Hassan Aden Hassan 41 years in prison each.
Rashid Charles Mberesero, a Tanzanian, got a life sentence for his involvement in the terror assault.
The three convictions are the first to result from a long-running investigation and prosecution.
According to the court, the four colluded with others to attack the university.
Andayi had previously acquitted Osman Abdi Dagane, a watchman at the institution, saying there was no evidence linking him to the attack.
The four were charged with carrying out the attack on Garissa University that left 147 people dead and 79 injured, most of them, students.
The siege ended nearly 15 hours after gunmen shot their way into the Garissa University College campus in a pre-dawn attack.
The attack came to a halt after four of the attackers were shot dead by Kenya’s Recce squad Commandos of the Kenyan GSU. The fifth terrorist was able to detonate his suicide vest causing injuries to some of the commandos.
The aftermath of the events led to the indefinite closure of the University and transfer of the surviving students to Moi University in Eldoret.
The University that was later reopened, now boasts of 1700 students and an additional 300, who have tendered their applications to secure a place in the institution of higher learning.
Students who preferred anonymity expressed their wish to have the suspects executed as they did to their former classmates.
