The spokesperson for Rwanda Correctional Service, CSP Sengabo Hillary, told IGIHE that on Wednesday, after all procedures related to Karasira’s release had been completed and only a few hours remained before he could leave prison, he took medication he normally used to manage a mental health condition.
“He would usually take the medicine and sleep for about six hours, as it helped him rest. However, because he took it in what appeared to be a suicide attempt, he consumed a large amount, which resulted in his death. He was taken to Nyarugenge Hospital, but doctors were unable to save him,” Sengabo said.
Sengabo added that Karasira died during the night at around midnight.
A medical report explaining the cause of his death is still expected, but preliminary findings indicate that he died after taking an excessive amount of medication.
Sengabo added, “All procedures required for his release had already been completed. What remained was the final search and exit process. That was the only step left when he took the medication and swallowed a large quantity of it.”
Karasira, widely known as Prof Nigga, had been convicted of inciting divisions among the public. He had completed the five-year sentence handed to him.
The sentence was issued on September 30, 2025, by the High Court Chamber for International and Cross-Border Crimes (HCCIC) based in Nyanza.
Based on the way prison sentence calculations are carried out within the correctional system, Karasira officially completed his sentence on May 6, 2026.
He had been charged with offenses including genocide denial, inciting divisions, and spreading false information.
Other charges included money laundering and failure to explain the source of his wealth, including cash found in his possession and funds held in various bank and Mobile Money accounts.
The prosecution had appealed the court’s decision to sentence him to five years in prison, but the appeal case had not yet been heard.
The correctional service stated that when releasing an inmate, it only follows the sentencing decision recorded in the electronic system used by the institution.
