The small Pittsburgh suburb of Bethel Park in Pennsylvania is reeling after the FBI named a young local man, Thomas Matthew Crooks, as the person who shot at Donald Trump during a campaign rally and shocked the nation.
Investigators believe that Crooks, armed with a semi-automatic AR-15 rifle, opened fire at the former president while he was addressing a crowd in Butler, Pennsylvania, leaving one audience member dead and two others wounded.
The 20-year-old kitchen worker was shot dead at the scene by a Secret Service sniper, officials said.
In his well-to-do hometown, however, neighbours are in shock, seemingly unable to grasp how a quiet young man is now accused in the shooting.
The FBI, for its part, has said only that Crooks was the “subject involved in the assassination attempt on the former president and that an active investigation was under way.”
Having established Crooks’ identity, police and agencies are investigating his motive.
So far, they have been unable to identify one.
On 15 July, the FBI said its forensic experts have successfully accessed Crooks’ phone, and they are examining it and other digital evidence for clues.
The inquiry into what took place could last for months and investigators would work “tirelessly” to identify what Crooks’ motive was, Kevin Rojek, the FBI Pittsburgh special agent in charge, said on the day of the shooting.
Speaking to CNN, Crooks’ father, Matthew Crooks, said he was trying to figure out “what the hell is going on” but would “wait until I talk to law enforcement” before speaking about his son.
Crooks’ family is cooperating with investigators, according to the FBI.
Citing three law enforcement sources, CBS has reported that his father called police after the shooting, although the nature of that call is still unclear.
In total, more than 100 interviews have so far been conducted.
Police sealed off the road to the house where Crooks lived with his parents. The search of the residence was completed on 15 July.
A neighbour told CBS that officers evacuated her in the middle of the night with no warning.
Bethel Park Police said there was a bomb investigation surrounding Crooks’ home.
Access to the area remains controlled, with a police vehicle blocking entry to the street in front of the house.
On Tuesday afternoon, yellow police tape could be seen strung up in front of the residence. The BBC had a clear view of the back of the residence, but could not see any movement inside.
Only residents have been allowed in or out of the street.
Law enforcement sources told CBS that they believe there was some degree of planning ahead of the shooting.
How much time was spent in that planning, however, remains the subject of an ongoing investigation.
Police believe Crooks acted alone, but are continuing to investigate whether he was accompanied to the rally.
What kind of person was he?
So far, a confusing – and at times conflicting – picture has emerged of who Crooks was as a person.
Speaking to local news outlet KDKA, some young locals who went to school with him described him as a loner, who was frequently bullied and sometimes wore “hunting outfits to school”.
Another former classmate of his, Summer Barkley, cast him differently, telling the BBC that he was “always getting good grades on tests” and was “very passionate about history”.
“Anything on government and history he seemed to know about,” she said. “But it was nothing out of the ordinary… he was always nice.”
She described him as well-liked by his teachers.
Others simply remembered him as quiet.
“He was there but I can’t think of anyone who knew him well,” one former classmate, who asked to remain nameless, told the BBC. “He’s just not a guy I really think about. But he seemed fine.”
Another classmate, who similarly did not want to be identified, described him as “intelligent but a little weird.”
Staff at Angelo’s Pizza, a restaurant in Bethel Park, told the BBC they were familiar with Crooks.
The restaurant’s owner, Sara Petko, said that staff members – some of whom were his classmates – thought he was a “loner” but that they were having trouble understanding how an otherwise quiet man turned to violence.
“It’s just crazy, and too close for comfort,” she said. “To think that someone at basically the start of his life could do this.”
Jameson Myers, a former member of the Bethel Park High School varsity rifle team who graduated alongside Crooks in 2022, told CBS that Crooks did not make the team.
“He did not even make the junior varsity team after trying out,” Mr Myers added. “He never returned to try-outs for the remainder of high school.”
Another former classmate told ABC News he “shot terrible” and “wasn’t really fit for the rifle team”. The school district said there was no record of Crooks trying out for the team and he “never appeared on a roster”.
Mr Myers remembers Crooks as seemingly a “normal boy” who was “not particularly popular but never got picked on or anything”.
“He was a nice kid who never talked poorly of anyone and I never have thought him capable of anything I’ve seen him do in the last few days.”
Max Smith, who took an American history course with Crooks, told the Philadelphia Inquirer that his former classmate “definitely was conservative”.
Mr Smith recalled a mock debate in which they both took part, saying: “The majority of the class were on the liberal side, but Tom, no matter what, always stood his ground on the conservative side.”
“It makes me wonder why he would carry out an assassination attempt on the conservative candidate,” he said.
Other community members said simply that they were shocked that the alleged perpetrator of the shooting could have come from the quiet, tree-lined streets of Bethel Park.
Among them was Jason Mackey, a 27-year-old local man who lives near the Crooks residence and worked at his school while he was a student.
While Mr Mackey said that he did not know Crooks personally, he is still reeling from a sense of disbelief.
“It’s just shocking. You wouldn’t think an event of this magnitude would come right out of your backyard,” he said. “It’s just a crazy situation.”
Who were the victims in the shooting?
One person was killed and two others were injured in the shooting.
All three victims are adult men and were audience members, CBS News reports.
At a news conference on Sunday, Pennsylvania Governor Josh Shapiro identified the deceased victim as Corey Comperatore, a 50-year-old volunteer fire chief who was killed when he “dived on his family” to protect them.
He said that Comperatore “died a hero”.
The two people injured in the attack have been identified as 57-year-old David Dutch and 74-year-old James Copenhaver.
Both men are Pennsylvania residents and are in stable condition.
A GoFundMe page, organised by the Trump campaign’s national finance director Meredith O’Rourke, was set up in the hours after the attack with donations going to the families of the injured.
It has so far raised more than $340,000 (£267,000).
In a post to his Truth Social platform, Trump said he was “shot with a bullet that pierced the upper part of my right ear” and said he felt the bullet “ripping through the skin”.
Blood was visible on Trump’s ear and face as protection officers rushed him away.
Trump is “doing well” and is grateful to law enforcement officers, according to a statement published on the Republican National Committee (RNC) website.
He travelled to Milwaukee, Wisconsin on Sunday, a day after the shooting, to attend the Republican National Convention.
