21-year-old girl killed in Machakos
Police in Machakos have arrested a key suspect in the tragic murder of 21-year-old university student Virginia Wayua Nzioki, whose body was discovered last week in Kariobangi, Machakos County.
The suspect, named William Kaia, was taken into custody on Wednesday, October 29, 2025, while he was hiding out in Mombasa. This arrest followed an extensive manhunt that kicked off right after the incident.
According to police reports, Kaia stabbed Wayua multiple times, resulting in her death on the night of October 9, 2025.
The victim’s mother, Josephine Ndunda, shared that after the horrific act, Kaia called the family to inform them that he had killed their daughter, a shocking revelation that left them reeling in disbelief.
On Wednesday, the 29th of 2025, Ndunda opened up about the tragic events and expressed her frustration over the slow police response leading up to the murder.
“Hata kama ni kitu alikuwa nayo yake angeniambia ningemlipa kuliko kumuua,” Ndunda said tearfully.
“Sioni kitu anaeza nipea au watu wao iniridhishe huyo mtoto wangu. Juu ni mtu tumemlipia, amepangiwa kuenda shule, kujoin university by January, na sasa hiyo yote imekatika.”
According to Ndunda, her daughter had warned about threats from the suspect before, but unfortunately, no swift action was taken.
“Kutoka hapo suspect akaanza kunipigia simu hiyo usiku akiniambia ni yeye alimua na alikuwa bwana yake. Msichana wangu hakuwa na bwana. Mimi kijana simjui hata venye alikuwa ananitumia message ndio aliniambia jina yake. Sijawahi mjua wala kumwona,” she added.
She further blamed authorities for inaction despite earlier reports filed with the police.
“Polisi Machakos DCI wangekuwa wakunisaidia, wangemsaidia. Ile wakati aliripoti , aliripoti tarehe tano, wangechukua hatua, wangechukua huyo msichana na wamshike huyo kijana kupitia huyo msichana. Walimwua tarehe tisa, si unaona hapo kulikuwa na nafasi ya kumshika,” she lamented.
The suspect is currently in custody at the Machakos Police Station and is set to appear in court on Thursday, October 30, 2025, to face murder charges.
