Anchorage police on Sunday were still searching for the person who shot and killed a 29-year-old man Saturday night inside the busy Dimond Center mall.

Police identified the victim as Edwing Matos of Anchorage. He was pronounced dead at a local hospital shortly after the 6:30 p.m. shooting, police say.

A man running from the scene was tackled by an off-duty court services officer just after the shooting -- but police now believe he was a friend of the victim, rather than the shooter, said police spokeswoman Marlene Lammers.

He was questioned and released.

"We don't have anybody in custody," Lammers said.

Contrary to initial police statements that the shooting appeared to be gang related, police said Sunday that the investigation found no indication that was the case. A sergeant at the scene of the shooting Saturday night had said one or more of the people involved were believed to be gang members.

Police are now looking for a man whom witnesses described as a light-skinned, black or Hispanic adult, roughly 6 feet tall and weighing between 220 and 240 pounds. He was seen wearing an oversized white sweatshirt and white baseball hat, police said.

Some witnesses said the man was wearing a wig or fake mustache, police said.

Police are asking anyone who knows the people involved in the shooting to call the police department at 786-8900, call Crime Stoppers at 561-7867 or submit tips at www. anchoragecrimestoppers.com.
