The alarm about ongoing shooting at Risbergska school in Örebro came at 12:33 on Tuesday.
In retrospect, the police have described it as that the first patrols were met with an inferno: deceased, injured people, screams, and smoke development.
On Thursday, Lars Bröms was on site at the school. He is the incident commander for the group within the police that has worked with identifying the dead.
Despite the bodies being gone, it was enough to establish that this was the worst crime scene one has ever experienced, says Bröms.
During his years as a police officer, he has, among other things, worked with the passenger ferry Estonia's sinking, the tsunami disaster, the Stureplan murders when four people were shot dead outside Sturecompagniet in Stockholm, and the terrorist attack on Drottninggatan.
One can never say that one sorrow is worse than another. But here we're talking about such evil and brutal death, says Lars Bröms.
"Right into the soul"
He doesn't hide the fact that it's a mentally demanding job. Not least talking to relatives in connection with the identification work.
It takes you right into the soul to meet the relatives who are in such desperate shock. It's tough.
How do you mentally prepare yourself to face a crime scene?
We talk a lot to each other in the group and prepare ourselves for it being tough. But we've been through this many times now, we know roughly what we'll be met with.
How do you process it afterwards?
Then we sit down and talk again. We're very open with each other and good at ventilating, says Lars Bröms.
Understands frustration
Eleven people have been confirmed dead in Tuesday's mass shooting, including the perpetrator.
On Friday – three days later – all victims were identified and relatives informed. Lars Bröms says he understands the frustration many feel about having to wait for news.
It's important to never take shortcuts in an identification process. We do everything to give the relatives an answer as soon as possible, he says.
