The unidentified male student claimed a man was seen on or near the roof of Lossee Center twice in the past two weeks as he looked down at the courtyard where Charlie Kirk's event was held, according to CNN. The person was last seen on the roof on September 3, he added.

Describing the man spotted on the rooftop as a "tall, skinny-ish white dude", the student said he was clad in dark attire and had a backpack.

He added that a professor at the school also saw the man on the roof and asked him, "Hey man, are you doing alright?"

The student also claimed that the photographs of the 'person of interest' looked familiar. He said he informed the FBI about what he witnessed but revealed that he is yet to get a response from the authorities.

The latest clip from the Utah Valley University campus released by the FBI shows the sniper running across the roof and jumping off the building after shooting Kirk. He has reportedly left behind palm and footwear imprints. The footage was shared by the bureau and the Utah Department of Public Safety during a press conference Thursday night.

FBI announced that they are relying on the public’s assistance in identifying the shooter and declared $100,000 reward as motivation for providing tips. The bureau has received over 7,000 tips regarding the assassination.
