Bait

Kieran heard the busy tone from the communicator.

Advance Rank Intuition allowed him to expand his hearing range to an unimaginable limit as well as increased his sensitivity for capturing noise or smell. 

Conventional means could not fool Kieran's Intuition, let alone when the communicator sounded without cover and in an open space.

However, Kieran didn't stop.

The three professors related to Index of Eat were all targets. Derton was already dead, and if he had not intervened and saved Tyrese, the professor would have been the second. Now, Eiderburgh going missing hit Kieran like an alarm clock.

There were some forces behind the scenes taking out anyone who was related to the Index of Eat.

And he would also be on that list.

Speaking from a particular aspect, Kieran was the fuse that ignited all this: he had been the one to bring the secretive Index of Eat up to the public eyes.
