OREBRO, Sweden (AP) 鈥� The shooter who killed 10 people in Sweden鈥檚 earlier this week was connected to the adult education center where he opened fire with at least one rifle-like weapon, law enforcement officials said Thursday.
Authorities said the gunman, who has not yet been officially identified, may have attended school there before Tuesday's violence on the school campus west of Stockholm. The shooter was later found dead with three guns and a large amount of unused ammunition next to his body, officials told a news conference. It was not clear how he died.
The school, Campus Risbergska, offers primary and secondary educational classes for adults age 20 and older, Swedish-language classes for immigrants, vocational training, and programs for people with intellectual disabilities. It is on the outskirts of Orebro, about 200 kilometers (125 miles) from Stockholm.
Some 130 officers arrived Tuesday after alarms summoned them to the school to find chaos across the campus. They described the scene as an 鈥渋nferno.鈥�
"Dead people, injured people, screams and smoke," local police chief Lars Wir茅n said during the news conference.
Officers found at least with serious gunshot wounds. Two of them remained in intensive care Thursday in serious but stable condition. The other three were in stable condition after surgery.
A sixth person was treated for minor injuries.
Police were forced to search the large school 鈥� 17,000 square meters (182,986 square feet) 鈥� to ensure that there were no other casualties. Authorities said the shooter had licenses for four weapons, three of which were found next to his body. Police have seized the fourth.
Investigators had not uncovered a definitive motive behind the bloodshed by Thursday. Police said there were no warnings beforehand, and they believe the perpetrator acted alone. Authorities said there were no suspected connections to terrorism at this point.
Days of 鈥榮hock and grief鈥�
In Orebro, a town of 160,000 that's considered Sweden's seventh-largest municipality, Thursday brought more sadness but still few answers.
鈥淚t has been two days of shock and grief,鈥� John Johansson, chairman of the town's municipal board, told The Associated Press. "We are still asking questions of why, still wondering what has happened. The outpouring of grief and togetherness has been enormous.鈥�
King Carl XVI Gustaf and Queen Silvia, as well as , visited Orebro on Wednesday and attended a memorial service.
Mourners elsewhere in the of roughly 10.5 million, where gun violence at schools is very rare, struggled to process the thought of mass violence in their own country.
"鈥淭his is not a Swedish problem, it鈥檚 a problem that we have seen throughout the world,鈥� Johansson said.
The shooting's online presence has prompted friends of Orebro resident Petter Jorman, a 60-year-old father whose son previously attended the school, to call and text him asking 鈥渉ow are you? Are you OK? I know you live close.鈥�
鈥楾he worst hours of my life鈥�
The shooting started , after many students had gone home following a national exam. as shots rang out, sheltering behind or under whatever they could find to escape the gunman and the gore. One woman with children feared she might never see them again, while another used her friend鈥檚 shawl to staunch the bleeding of a man who鈥檇 been shot in the shoulder.
鈥淭hose were the worst hours of my life. I did not know if I would get shot there and then, or in 10 minutes. You simply waited,鈥� Hellen Werme, 35, told the Expressen newspaper.
Guns in Sweden
Police wouldn鈥檛 say whether the shooter had multiple guns, nor would they say what kind of firearm was used in the shooting. While gun violence at schools is very rare in Sweden, people were wounded or killed with or axes in several incidents in recent years.

Applicants must also submit previously obtained hunting or target shooting certificates. Hunting certificates require people to pass a training course, while target shooters must be certified as active and experienced members of clubs.
All weapons must be stored in secure cabinets approved by the police. Applications for fully automatic weapons or one-handed weapons are only granted for exceptional reasons, and such permits are generally time-limited.
Permits are revoked if the weapon is modified to be substantially different from its original function.
