Detectives from the Directorate of Criminal Investigations (DCI) have intensified investigations into a series of murders linked to 23-year-old Joseph Njoroge Weru.
The sleuths claim to have unravelled a grim trail of calculated deception and brutality.
Investigators established that two young women — Mary Yamasei Merutuni (28) and Beatrice Nyawira Nyokabi (22) — were brutally killed in what detectives describe as carefully premeditated attacks.
Investigations show that on January 17, 2026, Yamasei left her rented residence in the Castle area of Naro Moru after the suspect persuaded her to accompany him for a “picnic” in the Karogoto area within Thiu Sub-Location, Nyeri County.
While approaching a hiking track adjacent to Karogoto Stream, the suspect allegedly got behind her and struck her repeatedly on the back of the head, killing her. He then dragged her body and dumped it in Karogoto Stream in a bid to conceal the crime.
The following day, locals discovered the body in the stream and reported the matter to Kiamachimbi Police Station, prompting officers to respond.
At the scene, investigators recovered a thick, blood-stained stick believed to be the murder weapon.
After the murder, the suspect allegedly returned to the deceased’s house, stole household items — including furniture — sold them at a second-hand shop and spent the night in her home.
Five days later, tragedy struck again.
On January 24, 2026, Beatrice Nyawira Nyokabi, a barber from Karindundu in Karatina, was reportedly lured by the suspect for a “hike” to Ithe Kauno village near the Gura River.
In a similar pattern, she was allegedly attacked from behind and fatally assaulted before her body was disposed of.
The suspect later sold her mattress, bed, woofer and other belongings at a second-hand furniture shop in Karatina town and allegedly intended to occupy her residence.
Following a relentless pursuit by DCI sleuths, the suspect was apprehended in Nyeri on February 13, 2026, and arraigned on February 16, 2026.
The court granted orders to detain him for 30 days pending completion of investigations.
Investigators were later led by the suspect to the house of the deceased, Beatrice Nyawira Nyokabi, in the Karindundu area within Karatina, where they recovered some of the suspect’s clothes and an imitation pistol.
The detectives then proceeded to Ithekahuno Village in Tetu Sub-County, where the suspect identified the scene where he murdered and left the body of Beatrice Nyawira Nyokabi on January 24, 2026.
The decomposed body was recovered at the same location on February 12, 2026, with the right hand missing.
Officers conducted an extensive search of the area and recovered a decomposed human right arm suspected to belong to the late Beatrice Nyawira Nyokabi.
The arm was documented and taken to Nyeri PGH Mortuary for preservation, pending autopsy.
Still in the company of the suspect, the team later proceeded to a hostel within Karatina Town to the room of a woman whom the suspect had earlier taken to the house of the late Beatrice Nyawira Nyokabi after murdering her.
Inside the hostel, officers recovered a jacket belonging to the suspect and the late Beatrice Nyawira Nyokabi’s house keys.
The suspect later led officers to a shop within Karatina Town where he had sold the late Beatrice Nyawira Nyokabi’s household items, including a mattress, a bed and a woofer.
Shop attendants confirmed the transaction, which was corroborated by CCTV footage retrieved from the premises.
Investigations remain active as detectives pursue leads to establish whether additional victims may be linked to the suspect, particularly in areas where he previously resided, including Nyandarua, Nakuru, Nyeri, Laikipia and Juja in Kiambu County.
The DCI urged members of the public with information regarding missing persons in the regions to report to the nearest police station as efforts to secure justice for the victims continue.
