Zamanbek Nurkadilov, an outspoken critic of Kazakh President Nursultan Nazarbaev, was found dead in his home.
The former Almaty mayor had bullet wounds to his chest and head.
Mukhamejanov said investigators had not yet ruled out any cause for his death, which comes ahead of presidential elections on 4 December.

Mukhamejanov also said that, according to Nurkadilov's family and friends, he had been depressed before his death.
