Fugaku had many suspects, and the first person he suspected was his son, Itachi Uchiha.
Itachi had awakened the Mangekyō Sharingan. He should have been able to take over Fugaku's position and become the next clan head, yet he remained torn between the clan and the village, refusing to reveal information about the Anbu members.
He had the ability to steal the Sharingan from the secret vault.
But Itachi should not have known of Izanagi and Izanami's existence, giving him no reason to carry out the theft.

For a moment, Fugaku even considered reporting the matter to the Hokage Building.
But the conflict between the Uchiha and the village had already reached the point of no return. There was no room left for reconciliation.
Either the coup succeeded and they took control of the Hokage Building, or it failed and the clan was exterminated. If they continued dragging things out, their strength would only be worn away bit by bit, until they could not even hold on to the Military Police Force.
