A search was continuing Thursday for the person who shot and killed Charlie Kirk at an event at Utah Valley University. Kirk , a prominent conservative activist who co-founded the right-wing advocacy group Turning Point USA, was 31.

Authorities have not yet identified or apprehended a suspect nor specified a motive, but on Thursday officials revealed new details about the shooter's movements and the investigation.

Officials took two people into custody in the wake of the shooting but later said neither was tied to the shooting and both were released.

Here is what we know so far about the ongoing investigation.
