Beaten and Left for dead: Love and rage behind murder of Umoja gym trainer

Alphy Migasha was known in Nairobi’s Umoja estate not just as a gym trainer, but as the embodiment of discipline, transformation, and quiet ambition.

A familiar figure at local fitness centres, Migasha built a reputation as a dedicated coach who believed physical fitness could change lives.

Clients, many of them young professionals and women, described him as patient, professional, and deeply committed to his work.

Regrettably, his untimely death is at the centre of a disturbing case that has sparked public debate regarding instructor-client relationships in gyms.

Migasha’s death on January 17, 2026, nearly four weeks after a violent assault, raises troubling questions about accountability and delayed justice, as crimes of passion continue to haunt families.

Even as they mourn the 35-year-old gym instructor, friends and family describe him as a hardworking man who turned his passion for fitness into a livelihood.

Based in Umoja One, he trained clients daily, often starting early in the morning and ending late at night.

Videos circulating online after his death show him during training sessions, calmly guiding clients through workouts, clips that have since become painful reminders of a life brutally cut short.

“He was disciplined, focused, and respectful. To many of us, he was more than a trainer. He was a motivator,” said a former client who asked not to be named.

Migasha was also the breadwinner for his family, a role his mother, Stella Okinda, says he took seriously: “He took care of us. Everything depended on him.”

According to police records and CCTV footage, Migasha’s ordeal began on the night of December 22, 2025.

He was seated outside a liquor outlet at Innercore when a man approached him. What started as a brief confrontation quickly escalated into a violent assault, leaving Migasha badly injured.

CCTV footage reviewed by investigators shows the assailant pulling Migasha to the ground and repeatedly beating him as bystanders unsuccessfully attempted to intervene. The attacker then walked away, leaving Migasha writhing in pain.

Family allegations

Family members allege that the suspect, a Kenya Defence Forces (KDF) soldier, accused the deceased of having an affair with his wife. Authorities have not publicly confirmed these claims, and the suspect has not been arrested as of publication.

Migasha’s family was alerted and rushed him to Mama Lucy Kibaki Hospital. Medical records indicate he sustained severe injuries, including a broken leg, fractured ribs, and serious chest trauma.

Doctors treated the fractures and placed him on medication, after which he was discharged. “He was in a lot of pain, but we believed he would recover,” a family member said.

In the days that followed, Migasha remained at home, trying to heal. But his condition deteriorated. On January 17, 2026, nearly a month after the assault, he began vomiting blood.

“He collapsed at home. By the time we realised how serious it was, it was too late,” his mother recalled.

Migasha died before he could be rushed back to hospital.

A postmortem conducted at City Mortuary by Chief Government Pathologist Dr Johansen Oduor provided clarity and deepened the family’s anguish.

“The blood clot travelled to the lungs, causing death. We believe it emanated from a leg injury he had,” Dr Oduor said.

Medical findings

The autopsy concluded that Migasha died from a pulmonary embolism, a blood clot in the lungs likely formed as a result of the fracture sustained during the assault.

Medical experts note that such clots can develop days or weeks after trauma, particularly when mobility is limited. While the immediate injuries may appear manageable, complications can be fatal if not detected early.

For Migasha’s family, the autopsy confirmed what they had long believed: his death was directly linked to the beating he suffered.

“He was hit on the chest, his leg was broken, and the blood clot went to the lungs and heart. There was no way he could survive. We call it justice,” said Okinda.

The family is now demanding the arrest of the suspect, arguing that the assault set off a chain of events that led to Migasha’s death. Under Kenyan law, an assault that later results in death can be treated as manslaughter or murder, depending on intent and circumstances, a determination that now rests with investigators and prosecutors.

The case was reported at Buruburu Police Station shortly after the December 22, assault. Buruburu Sub-County Criminal Investigations Officer (SCCIO) Simon Kirui has assured the family that investigations are ongoing.

“The case is actively being handled, and we will take appropriate action,” Kirui said.

According to police, the next step is to track down the suspect for questioning and possible prosecution. CCTV footage, witness statements, and medical reports are expected to form the backbone of the case.

However, the family says progress has been slow, and frustration is growing. “He is still at large. We are asking the police to act with urgency,” a relative said.

Authorities have also expressed concern over a rising number of assault cases that later turn fatal, warning the public that violence, even when not immediately deadly, can have devastating consequences.
