SPRING, Texas -- Two people tried to rob a Spring dry cleaning business, but the shop's manager didn't let them succeed, KPRC Local 2 reported.

Harris County sheriff's deputies said Nam-Duong Nguyen, the manager of the $1 Cleaners in the 18600 block of Kuykendahl Road, saw two people approach the store at about 6:35 p.m. Monday.

Nguyen said the two were wearing all black and he saw them pull masks over their faces.

The two crouched down and approached the front door, Nguyen told investigators.

Nguyen said he saw the two reach into the waistbands for an object. Nguyen, who has a concealed handgun license, pulled out his gun and fired toward the men about three times, investigators said.

The two tried to get away, but only one of them actually did. One of the men collapsed and died behind the northeast end of the strip center where the dry cleaning business is located, deputies said. The person had been shot, detectives said.

There was no identification on the body, officials said.

"The (second suspect was) possibly wounded … still on the loose," Sgt. Robert Shields said. "We got the hospitals on notification to alert us. We haven't received any reports back from the hospital."

Detectives do not have a detailed description of the second person involved.

The case will be referred to the Harris County grand jury without charges.

The store was open for business on Tuesday.
