Even with assurance by top detective George Kinoti that investigators have gathered sufficient evidence to prosecute prime suspect in Monica Kimani's murder, sources say that the case may take longer than expected.
Among the puzzling questions that remains unsolved, the Nation reports, is the motive of the murder which will play instrumental role in prosecution.
Inside her house, a detective concedes, there was no indication that the deceased struggled with assailant (s), thus pausing questions whether she was tricked or drugged before the murder.
When her body was retrieved, Monica's hands were tied up but their were no indication of injuries apart from slit throat, a further indication that the assailants were highly trained.
To this effect, a source adds, detectives are in South Sudan where Monica traveled from to establish whether the murder was planned from the neighboring country.
Already, Deputy Speaker of Sudanese government General Awet Akot has denied knowing the deceased despite claims that the two were lovers.
The murder weapon which is also important such crimanal trials is also missing. In the cells, Mr. Joseph Irungu, the Prime Suspect, despite circumstantial evidence linking him to the murder scene, has vehemently denied involvement.
Also tricky in the case is a second man pictured with Irungu from Monica's Kilimani apartment on CCTV.
Police are trailing the mysterious man who is said to have rushed to Mombasa to seek refuge in witch doctors but his whereabouts still remain at large.
On Wednesday, Mr. Irungu and his fiance Jacque Maribe will return to court for bail application and subsequent hearing.
