Nsereko Kyamukungubya Kiwanuka, the son of renowned businessman Mohan Kiwanuka and former Finance Minister Maria Kiwanuka, was found dead in his Washington, D.C. apartment on Wednesday, September 3, 2025, in what authorities and family believe was a sudden heart attack.
Nsereko (34) had recently completed his MBA at the University of Denver and had just started a new chapter in his life working as a financial advisor for a U.S.-based real estate firm.
According to his family, he had just received confirmation that he had passed his probation two months ahead of schedule, thanks to his rare competence.
“He was excited really excited,” a relative said. “He had finally found his rhythm abroad.”
With Monday marked as a public holiday in the U.S., Nsereko stayed indoors, as many do. When he didn’t show up for work on Tuesday, concern began to grow.
A close family friend contacted police. Officers arrived at the apartment, found the door locked, and forced it open.
Inside, Nsereko was found unresponsive. The television was still on, tuned to his favorite sports channel a haunting reminder of his final moments.
Before relocating abroad, Nsereko had worked at dfcu Bank in Uganda, where he quietly built his career with a passion for finance.
Those who knew him describe a man who was reserved but driven, kind but fiercely committed to personal growth.
In the U.S., he carved out a new space for himself, pushing through the challenges of adjusting to a new culture while excelling academically and professionally.
“He was living alone, yes but he was not isolated,” the family noted. “He kept in touch. He was happy.”
His death has sent ripples through both the Ugandan diaspora and Kampala’s elite circles. Friends and former colleagues have expressed shock, remembering a young man full of potential, taken far too soon.
Meanwhile, sorrows ripple through Uganda’s security circles following the sudden and unexplained death of Assistant Superintendent of Police (ASP) Musa Walugembe.
He was the man at the helm of the Special Investigations Unit (SIU), a division often associated with the country’s most sensitive and high-profile cases.
News of his passing broke early Wednesday morning, not through an official police statement, but via a deeply emotional tribute posted on X (formerly Twitter) by the Minister of State for Youth and Children Affairs, Balaam Barugahara.
“Afande Walugembe passed away peacefully in his sleep, cause of death unknown,” the minister wrote — a line that has since sparked whispers and speculation.
Walugembe wasn’t just any officer. He was a quiet powerhouse within the force, respected and, in some circles, even feared. Known for his integrity and ironclad discretion, his role in the SIU placed him at the intersection of power, secrecy, and justice.
Adding an extra layer to the story: Walugembe was also royalty, a prince from Nakifuma, deep within the Buganda Kingdom. His dual identity, as both a guardian of law and a son of tradition, made him a unique figure in Uganda’s power structure.
“Uganda has lost a brave son. His legacy of loyalty and service will forever be remembered,” Minister Barugahara added.
But as condolences pour in, questions linger. How does a man of his stature, in the prime of his service, die so suddenly and quietly with no known cause? Was it truly natural or is there more to this story?
