"The reason why I am talking to you is to let know, all the other families, to let know we are so sorry and our hearts is with them," she said Wednesday. "I hope they can understand that we are sorry, too. We wish that something like that never, ever happen."

'We are good people'

Armed with a shotgun, a .38-caliber handgun with a backpack full of ammunition and a bandolier of shotgun shells around his waist, police said Talovic began shooting as soon as he got out of his car at Trolley Square. By the time the gunfire stopped, six people were dead, including Talovic, who died in a shootout with police. Four people were wounded.

"There is still no known motive," Salt Lake City police detective Robin Snyder said Wednesday.

Addressing concerns from some that Talovic's Muslim beliefs may have played a role, Snyder said there was no evidence that was the case. The FBI said Wednesday that it had determined terrorism did not play a role in the shooting rampage.

Omerovic said Talovic was not a terrorist.

"I want to make sure that people don't think about us that we are terrorists or something like that," she said. "We are good people, just like everybody, and we want to be nice to everybody."

Detectives were allowed by Talovic's mother to search their home without a warrant early Tuesday, Snyder said. Salt Lake City police would not say what — if anything — was seized from the house.

Investigators had also not found any type of suicide note as of Wednesday, Snyder said.

The case is technically considered "closed" from a police investigation standpoint, because the gunman is dead. However, Snyder said, homicide detectives will continue looking for a motive.

Talovic's family wants to know where he got the guns, suggesting he did not have them at home.

"We want to know who signed for the guns and all the things that he had with him," Omerovic said. "We don't have any ideas how he get all that. We want to find who did that."

Agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives are investigating where Talovic got a .38-caliber pistol, which is illegal for an 18-year-old to possess.

A child of war

The war in Bosnia-Herzegovina forced the Talovic family to live as refugees. From 1993 until they emigrated to the United States in 1998, they were on the run, moving from village to village.

They lived near Srebrenica, where more than 8,300 Muslim boys and men were killed in 1995 by Serb forces loyal to ex-Yugoslavian leader Slobodan Milosevic. Sulejman Talovic was 7 years old then.
