SALT LAKE CITY (AP) - Trolley Square seemed an unlikely place to celebrate love, just two nights after the shopping mall was turned into a shooting gallery.

But many diners kept their Valentine's Day reservations at Rodizio Grill, inspired to support merchants at a time when five deaths at the hand of a young, enigmatic gunman have left the city scrambling to understand why.

"It's like with what happened with 9/11 and getting people back on planes. It made it more important to come here tonight," said diner Loggins Merrill, 32.

The mall reopened Wednesday even while signs of Sulejman Talovic's violent storm were evident - painted plywood over broken windows and patches over countless bullet holes on walls and pillars.

Talovic, 18, shot nine people at random Monday night, killing five, before dying in a shootout with police.

The Bosnian immigrant was not motivated by Islamic belief or an act of terrorism, the FBI and a family member said.

"We are Muslims, but we are not terrorists," said an aunt, Ajka Omerovic, adding that "we couldn't believe our eyes" while watching TV reports of the rampage.

Bosnia's U.S. ambassador planned to visit the city Thursday in the search for answers to the shooting. Bisera Turkovic was scheduled to join fellow countrymen for lunch at the Bosna Restaurant and attend an evening memorial at the downtown library.

Authorities were at a loss to figure out what motivated Talovic and how he got his hands on a gun.

"He was just walking around and shooting everybody he saw," said FBI agent Patrick Kiernan, adding there was no reason to believe the spree was motivated by religion or politics.

The Bureau of Alcohol, Tobacco, Firearms and Explosives is investigating how Talovic got a .38-caliber pistol, which was illegal to possess. He also had a shotgun, a bandolier of shotgun shells under his trench coat and a backpack full of ammunition.

"You can buy long guns at 18. That's not a problem," said Lori Dyer, in charge of the local ATF office. "The handgun he shouldn't have had, so obviously we're going to look at where he got that gun."

The dead were Jeffrey Walker, 52, Vanessa Quinn, 29, Kirsten Hinckley, 15, Teresa Ellis, 29, and Brad Frantz, 24.

Talovic lived with his parents and three younger sisters in a tiny ranch house on the west side. His father works long hours in construction. Neighbors described the boy as a loner who dressed in black.

His parents, Suljo and Sabira Talovic, do not speak English well and have refused to answer the door, drawing their window blinds tight. A school counselor close to the family was muzzled by superiors when an Associated Press reporter showed up at Jackson Elementary.

Immediately before the shootings, Talovic worked his regular shift as a general laborer at Aramark Uniform Services, an industrial launderer and uniform-rental company, manager Trent Thorn said.

Talovic and his family moved to the U.S. after living as refugees in Bosnia for five years, people close to the family still living in Bosnia told the AP.

Talovic was only 4 when he and his mother fled their village of Talovici on foot after Serbian forces overran it in 1993, they said.

"Many left the village, but only a few made it," said Murat Avdic, a family friend, who believes Talovic's exposure to war, even at an extremely young age, somehow had a role in the Utah tragedy.

At Trolley Square, the site of the carnage, mall managers opened doors less than 48 hours after the shootings. Eleven of 36 stores reopened, with many more expected by Friday, spokeswoman Alicia Bremer said.

"Our lunch crowd was really big," Rodizio Grill manager David Knighton said as Valentine's Day customers filled dinner tables. "People came up to me and told us that they wanted to come down and support us. It's been a really emotional day." ---
