At about 8:24 p.m. Tuesday, Houston Police Department officers were called out to the 4300 block of Capitol Street after reports of a shooting.
HPD Lt. Larry Crowson said the victim had arrived at a home in the area, and an argument ensued over a shoe sales transaction.
"Some kind of argument broke out over who was paying or how much was going to be paid," Crowson said.
During the argument, the victim and the suspect took out their guns and began firing. The victim was shot in the arm. He was taken to the hospital, where he was pronounced dead.
The suspect was detained on scene.
An investigation continues into the case.
The area where the shooting happened includes Eastwood and Broadmoor, which is home to about 10,000 people, according to ABC13's Neighborhood Safety Tracker.
Data shows the area has seen three homicides and 267 assaults in the last 12 months.
