Mbobu, a former chairman of the Political Parties Disputes Tribunal, was shot dead on September 9, 2025, in what appeared to be a well-planned hit.
Investigators admit they are facing serious challenges. The biggest setback is the lack of working CCTV cameras along Magadi Road, where the lawyer was ambushed.
Without video evidence, police have little to connect suspects to the brutal attack.
This has already led to the release of three people earlier held as persons of interest.
More than 15 individuals have been interrogated, including colleagues, clients, boda boda riders at the scene, and bank staff linked to his transactions.
Authorities suspect that his professional work or recent financial dealings could be linked to the killing.
Interior Cabinet Secretary Kipchumba Murkomen has acknowledged the difficulty investigators face.
He said unlike the murder of MP Ongondo Were, which was solved using CCTV footage, the Mbobu case is complicated by the absence of cameras along the route where the shooting happened.
“It is not easy because the area where this incident happened had no CCTV cameras,” Murkomen explained, though he insisted valuable leads are being pursued.
The Director of Public Prosecutions, Mulele Ingonga, has directed police to speed up investigations and provide a detailed report within a week.
He urged members of the public with any information to come forward, stressing that the rule of law must prevail.
Mbobu was attacked while driving home. Witnesses say two gunmen on a motorcycle blocked his car, shot him in the chest and neck at close range, and sped off while firing in the air.
He died instantly from multiple gunshot wounds.
Despite government assurances, many fear the killers could escape justice, just like in other high-profile murders where evidence ran cold.
Mbobu was laid to rest at his family home in Mua, Machakos County, even as Kenyans wait anxiously for answers on who killed him—and why.
