The gunman who killed 10 people and wounded several others in Sweden may have been connected with the adult education centre where he opened fire, police have said.
Detectives are still trying to establish a motive for Tuesday's attack in Orebro, the worst mass shooting in the country's history.
Sweden has been left reeling as more details emerge, with the names of victims yet to be confirmed by police.
In an update on Thursday, police said the gunman - who has been named in local media as Rickard Andersson - may have attended the education centre as a student.
Officers said the 35-year-old was found dead after the attack with a large amount of unused ammunition nearby.
They added that the shooter had licences for four weapons, three of which were found next to his body.
"We have found several weapons in the school. They are so-called long guns, rifles," a police spokesperson said.
Andersson is said to have been unemployed for more than 10 years and is reported to have attended a special class for people with Asperger's and high-functioning autism. However, it is unclear whether this was at the same education centre.

The head of the local police, Roberto Eid Forest, said the centre's large premises meant it took a long time for officers to search the campus and ensure there were not any more victims.
Police heard gunshots when they arrived and initially thought they were being fired at, he added.
Meanwhile, mourners have continued to leave tributes to those who died at a makeshift memorial near the scene.
One of them, Malin Hilmberg, 37, said: "We heard about it [mass shootings] in different parts of the world, but of course, it's a shock. It's your hometown and so many lives destroyed. It's hard to find words."
