We earlier reported that the shot seems to have been fired from an "elevated position" in an academic building - either from a rooftop or open window.
A source now tells our US partner, CBS, that the attacker appears to have fired from the roof of the school's Losee Center.

Image source, ReutersIt's become very quiet - and very sombre - at the White House following President Trump's announcement that Charlie Kirk has died.
Just a few moments ago, members of the White House press pool gathered outside after being told that the American flags at the White House were being lowered to half-staff.
It was very quiet outside when that announcement came through, and the only sounds I heard for a few moments were the shutters of cameras and a few reporters speaking softly into cameras, or amongst themselves.
The flag at the North Lawn of the White House came down at exactly 17:20pm EST. The flag on the South Lawn has also been lowered.
There are few staffers still immediately visible in the offices.
Earlier, there was a sense of clear, visceral sense of shock among them. Kirk had close ties with the president, his family and members of the administration - and many of even the younger, junior staffers are members of his enormous, intensely engaged audience of young US conservatives.
Former President Barack Obama has posted on X, offering his condolences to Kirk's family.
"We don’t yet know what motivated the person who shot and killed Charlie Kirk, but this kind of despicable violence has no place in our democracy," he writes.
"Michelle and I will be praying for Charlie’s family tonight, especially his wife Erika and their two young children."
We can bring you some more reactions from Trump's administration, after the death of Charlie Kirk.
Secretary of State Marco Rubio said he is "heartbroken" and "outraged", calling his death an "assassination". "Charlie Kirk's commitment to America's future generations and sense of patriotism will resonate for decades to come," he said.
White House Deputy Chief of Staff Stephen Miller called Kirk "the most extraordinary husband and father".
"America has lost one of its greatest champions," Miller said. "All of us must now dedicate ourselves to defeating the evil that stole Charlie from this world."
We're now hearing from another eyewitness who was at Utah Valley University where Charlie Kirk was speaking before he was shot.
Adam Bartholomew says he was at the event interviewing counter protestors that were speaking against Charlie Kirk's presence on campus.
He says he heard a shot and everybody dropped to the floor.
"There was confusion and people started scrambling for the exits," he tells the BBC.
Bartholomew says there were about 50 or 60 people protesting against Kirk.
Prior to the shooting he says the mood at the event was "great" and people were chanting "U.S.A".
The anti-Kirk protestors were chanting in response with profanities against Kirk, he says
"Several people are in tears," he says of the atmosphere after the shooting.
Bartholomew says he was "surprised" that there was no security at the event. "Nobody stopped me or searched my bag."

From his restaurant, Sin Maran didn't hear the shooting - but he saw scores of students fleeing the scene.
"The location is very close to me and then we saw people running," he tells me.
Maran, who owns the university campus sushi restaurant Fishbone, says one person ran into his store to hide and told him that a speaker had been shot.
Video shared with the BBC shows dozens of students sheltering in the restaurant after the shooting.
Maran says when he learned of the shooting, he "turned off the lights everywhere". After 30 minutes, he got a notification to evacuate the campus.
Warning: This video contains distressing images.
Hundreds of students had gathered at the event were Charlie Kirk was shot earlier today.
He had been answering a question from a student when a single shot was fired.

President Donald Trump has ordered flags to be flown at half mast in the US.
"In honor of Charlie Kirk, a truly Great American Patriot, I am ordering all American Flags throughout the United States lowered to Half Mast until Sunday evening at 6 P.M.," he says in a social media post.
Former US President Joe Biden has offered his condolences to Charlie Kirk's family in a post on social media just now.
"There is no place in our country for this kind of violence," he writes.
"It must end now. Jill and I are praying for Charlie Kirk’s family and loved ones."
Three sources familiar with the investigation into the shooting have told CBS News, the BBC's US partner, that a search for the suspect is still ongoing.
A further two law enforcement sources said that police have not yet declared the scene safe for the public.

UVU police said they are currently going "building to building" to conduct the evacuation.

Kirk was one of the most high-profile conservative activists and media personalities in the US and a trusted ally of President Donald Trump.
Kirk, 31, who the president said died after a shooting at a Utah college on Wednesday, was known for holding open-air debates on campuses across the country.
In 2012, at the age of 18, he co-founded Turning Point USA, a student organisation that aims to spread conservative ideals at liberal-leaning US colleges.
His social media and eponymous daily podcast often shared clips of him debating with students about issues such as transgender identity, climate change, faith and family values.
Kirk was married and had two young children.
Utah Governor Spencer Cox says he has just spoken to President Trump after Kirk was shot at a Utah Valley University campus.
"Working with the FBI and Utah law enforcement, we will bring to justice the individual responsible for this tragedy," he says.
Meanwhile, Utah Senator Mike Lee has also tweeted. He describes Kirk as an "American patriot".
"The terrorists will not win. Charlie will. Please join me in praying for his wife Erika and their children. May justice be swift," Lee says.
