COMMERCE CITY, Colo. -- Police are still looking for suspects in the murder of a store owner gunned down Wednesday afternoon inside a dollar store in Commerce City.

Dung Viet Le's wife, sisters and daughter visited the crime scene Thursday to lay flowers outside the building. They later went inside the store with detectives to try and help with the investigation.

A customer walked in to the Dollar Value Plus store at East 63rd Place and Ivy Street around 1 p.m. and found Le bleeding on the floor, police said.

The customer who found the man ran to a neighboring coin laundry for help.

"I asked him what happened? He said the owner just laid down on the floor. I said what happened? ... Maybe he got shot because there ... there is blood all over the head," said Sokchheng Mam, who works in the shopping center.

The victim was taken to the hospital, where he died.

Commerce City police have released little information about the shooter, or about the victim.

His family said Le's soldier father fled Vietnam at the end of the war in the 1970s, having fought for the American-supported South Vietnamese, but the rest of the family stayed behind. They said Le came to the United States in 1991.

Relatives said Le was recently laid off as a design engineer and was working at the store every day, but was having trouble making the lease payments.

The shooting has neighboring businesses worried that it was a botched robbery and they said they are afraid.

Anyone with information about the investigation should contact the Commerce City Police Department.
