Monica Kimani's killer was a highly trained assasin and has left the police struggling to gather evidence, the Nation has reported.
Among issues that the police are struggling to investigate is how the deceased was unable to struggle during the fateful night and difficulty in locating the weapon used to execute the murder.
“Her body did not have injuries consistent with a big struggle against an assailant,” a Nation source conversant with the investigation, but who comments anonymously on ongoing investigations, said last evening.
There were also no signs of struggle in the apartment, as one would expect. The source’s reading of the scene of crime, he said, indicated that Ms Kimani was tied up “like a goat”.
“We know they had been taking wine,” the source noted, and wondered: “Was she drugged?”
At police cells, investigators claim, prime suspect Joseph Irungu has refused to give any hint even as fingerprints dusted from furniture and the glass wine indicates that he was in the victim's house during the fateful day.
Also, the biological identity of the killer may take longer than expected since most of 'vital' evidence may have been cleared.
Detectives are said to be relying on circumstancial evidence like the fingerprints, phone call data and evidence from neighbours but are yet to ascertain involvement of Irungu in the murder.
Mr. Irungu, who is remanded at Industrial Area prison, will appear alongside his fiance Jacque Maribe on Wednesday in court for bail application.
