Houston police said they received a call of the shooting at about 11 a.m. on Tuesday at the Valero gas station in the area of Northborough and Meadowfern Drive.
According to investigators, 34-year-old Demrick Thomas and his girlfriend were parked next to another vehicle when he caused a "door ding" to the vehicle next to them.
An altercation between Thomas and a person inside the damaged vehicle took place, escalating into Thomas being shot multiple times.

He was rushed to the hospital, where he died.
Video taken from the passenger side of Thomas' car captured the heated exchange and the moment he stepped out of the car to confront the man.
"Why did you kill my child? I need to know why," said Thomas' mother, Kimberly Jackson, during an interview with ABC13 on Wednesday.
Thomas was a father of seven. His youngest child was two years old.
"She was crying for her father [Tuesday] night," his mother said.
Police said the suspect may have driven away in a white Mercedes.
HPD later released photos of a female person of interest and the Mercedes Benz in question. The vehicle is believed to have been a 2008 to 2012 Mercedes C Class 250, 300 or 350 sedan.
"She was driving a white Mercedes C Class at 11:15 a.m. [Tuesday] at 12800 Northborough when a passenger (suspect) fatally shot a man," police tweeted.
