After the killings, Anguyo allegedly fled the prison and went to Saza Trading Centre, where he committed two aggravated robberies while still armed with the SMG rifle.
The High Court sitting at Kiboga has convicted Prison Warder Anguyo Moses on seven criminal charges after he pleaded guilty to murdering four people, committing two counts of aggravated robbery and threatening violence against the Officer in Charge of Kiboga Government Prison, SP Ivan Niwagaba.
Anguyo pleaded guilty to four counts of murder relating to the deaths of Assistant Superintendent of Prisons (ASP) Catherine Hope, Principal Officer (PO1) Akishuri Bright, Sarah Ayebare and her infant son, Salson Niwagaba.
He also admitted to two counts of aggravated robbery involving clothes allegedly stolen at gunpoint from Nabayiga Mary and Kamusiime Grace, as well as one count of threatening violence arising from allegations that he threatened to shoot or kill SP Niwagaba.
Prosecution told court that on February 23, 2026, Anguyo was on duty at Sentry “A” at Kiboga Government Prison, armed with an SMG rifle, when he allegedly became insubordinate during a supervisory inspection by SP Niwagaba and ASP Catherine Hope.
He had reportedly been found using a mobile phone while on duty, contrary to prison operational directives.
According to the prosecution, when Anguyo was ordered to hand over his firearm, he became violent, cocked the weapon and pointed it at SP Niwagaba. The firearm initially malfunctioned, but Anguyo allegedly re-cocked it and fired at the officer, who escaped unharmed.
The incident subsequently turned into a shooting spree in the prison premises. Anguyo allegedly shot dead Sarah Ayebare and her infant son, Salson Niwagaba, who were in a vehicle within the prison yard.
ASP Catherine Hope was also allegedly shot dead in a toilet at the District Health Officer’s premises.
PO1 Akishuri Bright, who responded to the gunshots believing that prisoners were escaping, was also fatally shot by Anguyo, according to the prosecution.
After the killings, Anguyo allegedly fled the prison and went to Saza Trading Centre, where he committed two aggravated robberies while still armed with the SMG rifle.
He allegedly robbed Kamusiime Grace of a pair of black jeans and Nabayiga Mary of an Arsenal jersey.
The prosecution further alleged that Anguyo later discarded his prison uniform and abandoned the firearm in a bush in Kibiga Sub-County before fleeing the area.
He reportedly travelled to Arua and subsequently crossed into the Democratic Republic of Congo, where he was later arrested in a joint Uganda-DRC operation in Aru.
On Monday, August 31, 2026, Anguyo pleaded guilty to all seven charges, prompting the High Court to convict him on each count.
Both the prosecution and defence have made submissions relevant to sentencing, with the prosecution asking court to impose the maximum penalty of death.
The court will on Tuesday, September 1, hear submissions from the victims of the crimes, including the families of the deceased, the Uganda Prisons Service and members of the community, before delivering the sentence.
The case is being prosecuted by the Office of the Director of Public Prosecutions (ODPP), represented by Assistant Director of Public Prosecutions Dr Daisy Nabasitu and Senior State Attorney Stephen Arion.
Anguyo is represented by defence lawyers Swaibu Male and Cate Nakamya.
The case is being presided over by Hon. Lady Justice Jane Okuo Kajuga.
The ODPP said the conviction marks a significant step towards securing justice for the four deceased persons, their families and the victims of the other offences.
The prosecution added that it remains committed to ensuring that persons accused of serious offences are brought to justice while upholding the interests of victims and their families throughout the criminal justice process.
