This is according to his lawyer Charles Mugane who spoke to local media.
Mugane says so far, the artiste has honoured summons before the investigating officer since the incident which occurred on February 22, 2023.
"My client is cooperating with the ongoing investigations. He has appeared for summons since the death of Geoffrey," Charles Mugane said.
At the same time, he sent a condolence message to Mwathi's family, saying the situation was "difficult on his client as well as his friends".
"To Jeff's family, we want to send our condolences. This is a difficult matter for my client and his friends, in the end, the truth will become clear," he added.
Mwathi at DJ Fatxo's apartment
A police statement recorded by the DJ Fatxo's cousin and driver at the Kasarani Police Station indicates that Mwathi, who was an interior decorator, died after jumping from Fatxo's Redwood apartment on the 10th floor along Thika road after partying together.
This was after the two had met through a referral.
The apartment's CCTV footage captured Mwathi with DJ Fatxo and three other unidentified women going to the DJ's apartment around 3 am before another man who is the DJ's relative joined them later in the night.
At 4 am, the DJ was captured leaving the apartment with the three women. Mwathi remained behind with the two men.
Later, two men would be seen surveying the apartment's parking lot and his cousin was seen making calls before returning to the apartment.
About seven minutes later, Mwathi fell from the apartment.
His uncle Muchoki Mwathi disclosed that he had his pants pulled down to his knees at the time of his death.
It remains unclear if he was sexually assaulted before his death since his autopsy was carried out after 72 hours had elapsed.
DJ Fatxo maintains Mwathi jumped to his death which his family has dismissed.
The matter remains under investigation.
