Was it a fall or a push? This is the question that DCI homicide investigators will be seeking to answer starting Monday when investigations into the controversial death of 23-year-old interior designer Geoffrey Mwathi alias Jeff.

On Friday, homicide investigators took over the case from their Kasarani DCI counterparts.

This followed a directive by Interior CS Kindiki Kithure who asked DCI chief Mohammed Amin to have the matter taken over by DCI headquarters.

On Friday, investigators from the homicide unit and with their Kasarani counterparts visited the 12-storey building where Mwathi fell from.

The new investigations team spent the better part of the day trying to reconstruct events at the building.

An initial report filed at Kasarani police station on February 22 stated that an unidentified man had committed suicide by jumping from the building.

Detectives familiar with the matter said police were called and informed that a man had committed suicide.

The suicide theory has since been dismissed by Mwathi's family who claimed that their kin could have been pushed.

At least five people among them the popular DJ Lawrence Njuguna, also known as DJ Fatxo have been lined up for questioning. The DJ has since distanced himself from the death.

Others set to record statements are two friends who were in the house where Mwathi and the friends are said to have been partying before his death.

Preliminary investigations have revealed that Mwathi, was reportedly hired by the DJ for an interior decor job.

How Mwathi ended up dead outside the DJ's house at Park estate after their meeting is now the subject of police investigations.
