Hull said that surveillance footage showed Robinson’s vehicle entering a campus parking garage, before a man wearing a maroon shirt, Converse shoes and grey or olive shorts was seen walking across campus.
The same man was later seen returning to campus, buying food from Chick-fil-A and heading into a wooded area near the university, Hull said.
When he reappeared on campus, around 90 minutes before the shooting, the man was wearing different clothes and seemingly walking with a limp, according to the witness.
Footage then showed the suspect making his way to the Losee Building on the campus and rolling over a railing onto the rooftop.
Shortly after the fatal shot rang out, the same man can be seen running across the roof, dropping down with an unknown object in his hands and making his way off campus, Hull testified.
A rifle was later recovered “in the wooded area where we believe Mr Robinson entered the wooded area”, Hull told the court.
The agent also said that, in the early hours of 11 September – while a manhunt for Kirk’s killer was underway – an officer near campus had made contact with Robinson and noted his licence plate.
