Fifteen-year-old Natalie Samantha Rupnow went to her Madison, Wisconsin school as usual on Monday morning and waited three hours before pulling out a handgun and opening fire at students and teachers.
She killed a teacher and a fellow student in the rampage and left six injured. Four were taken to hospital, with two left in critical condition.
Rupnow was found with a self-inflicted gunshot wound after police arrived on the scene, and died in the ambulance on the way to hospital.
They arrived three minutes after a second grader reported an active shooter at the Abundant Life Christian School at 11am yesterday, as students braced under their drilled lockdown procedures.
The shooting prompted an outpouring of grief in the community and calls from President Biden to enact gun-control legislation to prevent further massacres.
Similar calls have gone unheeded after almost every school shooting in recent memory.
But as investigators try to piece together exactly what happened yesterday morning, several unanswered questions remain for police to address.

Police raided Rupnows family home eight miles away from the school on Monday night, with SWAT teams deploying stun grenades on the property.
Rupnow is alleged to have left behind a manifesto shared widely online, which investigators are now sifting through - but are yet to confirm its veracity.
A law enforcement source told CNN that Rupnow had been dealing with problems and expressed some of those in writings, which they are now reviewing.

How did Natalie Rupnow get hold of the weapon?
Rupnow waited three hours before pulling out a 9mm pistol and attacking her fellow students and teachers, an official told AP.
Police recovered the weapon after the attack but are still working to establish how she got hold of it.
Cops also confirmed that shooter Rupnow was not on their radar and had no prior interactions with her before Monday, though they said a probe would confirm that.
Barnes said the suspect’s home had been searched on Monday - and police are seeking additional search warrants.
It has not yet been confirmed if Rupnows family were gun owners.
Did Natalie Rupnow have a boyfriend?
Police have not commented publicly on Rupnows relationships, except to say the family are cooperating with their investigation.
But one social media user claimed to have spoken to Rupnows alleged boyfriend, understood to have shared a manifesto police are now trying to verify.
We haven’t been able to verify that it’s authentic. We’re certainly aware that it’s been posted and the person who posted it, alleged to have a connection with the victim, Barnes said of the document.
The social media user said only that they had spoken with the alleged boyfriend of Rupnow, who said they knew her by Samantha, not Natalie.
The user cited the alleged boyfriend in dispelling rumors Rupnow was transgender, and said they had directed them to the alleged manifesto.
Her boyfriend says the photo that is making the rounds is not how he remembers her, and believes it was somewhat edited “to make her look worse," they claimed.

Was Natalie Rupnow transgender?
Amid wide speculation on social media as to the shooters motive and identity, Chief Barnes told a press conference resolutely that rumors were not helping the probe.
I dont know whether Natalie was transgender or not. And quite frankly, I dont think thats important at all, he said.
I dont think whatever happened today has anything to do with how she or he or they may want to identify. He added that it didnt really matter for the time being and that it was just not helping.
For what were doing right now, today, literally eight hours after a mass shooting in a school in Madison, it is of no consequence at this time (what gender the shooter was), he said.
He also claimed that he had no knowledge of any previous interactions with Rupnow: I think if there were, we certainly would have had some type of intervention, but Im not aware of that.
