Key Suspect?
FBI Should Search for Stone Lambert
At this time, there is no proof that he is at all connected to the shooting. But, he was humiliated by Charlie in public, and may have had a bone to pick with him.
He suffered an embarrassingly and quite humiliating defeat in a debate against Charlie Kirk, to which he brought a megaphone on April 1 this year. He appears to have been an adult student (of mature age) at the University of Oklahoma. Since then, he has been running a small independent construction business where he works as a contractor.
Other reports indicate that he lost his brother and his mother in the last two years.
This is one of the factors raising suspicions among many on social media at this moment.
In the full length video (not shown below) of the debate between the two, the individual indeed appears to display quite peculiar outbursts of aggression, both in the way he uses the megaphone, his fits of rage, his profanity, and his facial expressions.
