Jane Murugi's husband, Stephen Ndoro has been arrested, as a key suspect following her death under unclear circumstances.
Jane is Githunguri MP Gabriel Kago's sister.
Ndoro' arrest comes after his wife was found dead on Friday morning at their Membley Estate home in Ruiru, Kiambu County.
Speaking to K24 Digital, Ruiru police boss, Mutwiri Ringera confirmed that Ndoro has been arrested as investigations into the unfortunate death of Ms Murungi continues.
Reports indicate that Murungi, 41 years old was found dead while seated on the toilet seat.
Police have dismissed reports that she committed suicide after a scuff was found around her neck.
“A scarf tied to a necktie was found hanging from the toilet window,” Mr Ringera told K24 Digital.
The police believe someone killed her and tried making it look like suicide.
According to Ndoro's statement, he found her dead in the toilet at around 5 AM.
Murungi was a senior nurse stationed in Machakos County, while Ndoro is a medical doctor in Makueni County.
At the time of her death, she was on leave. She left behind a two months old baby.
Her brother, MP Kago has asked the police to do thorough investigations so that the cause of her unfortunate death can be known.
