When and where did the shooting happen?

Charlie Kirk was speaking to around 3,000 people from under a small white tent on the campus when he was shot.

The event was part of his"prove me wrong" series, which saw the right-wing influencer visit campuses across the country and debate contentious subjects like gun control, free speech, LGBTQ+ rights and abortion rights with left-wing students.

The event began at roughly 12pm local time.

Kirk was taking questions about mass shootings and gun violence when, at roughly 12.20pm, he was shot.

Where did the shot come from?

In a statement on Thursday, the FBI said they had tracked the gunman's movements onto the campus,"through the stairwells, up to the roof, across the roof, to a shooting location".

They said they first tracked his movements from 11.52am, when they said he arrived on campus.

Videos from the event show the gunman was on top of the Losee Centre building - just over 130m away from where Kirk was speaking, according to an online measuring tool.
