It happened around 9pm at the Subway off MLK and Malmedy.
Police say two young men armed with guns walked in to rob the restaurant and ordered two employees to give them some cash. After holding up the employees, their attention turned to customer Christopher McGrew.
Authorities say the armed men struggled with McGrew, 36, as they tried to search him for valuables, and shot him to death, all for very little return on the crime.
"They're estimating less than $100," said Sgt. Thomas Bigg with the Houston Police Department.
Family members are now mourning his loss.
"He was good people. He was a bright person, stayed in church, didn't bother nobody," his brother, Joe Jackson, said.
Family described McGrew as a person who minded his own business and say they believe he was at the wrong place at the wrong time.
"I want justice to be done. I want them to be caught and I want justice to be done," the victim's aunt, Jacquelyn McGrew, said.
Meanwhile, other customers are still in shock.
"This morning I stopped here to get something and I found out somebody got killed here," said customer Modest Elridge.
Although Elridge says she usually stops by the Subway in the morning, it doesn't matter what time of day she's out in her neighborhood, the worst possibilities are never far from her mind.
"I think about it while I'm eating, thinking somebody might come through the door with a gun. You don't know. You never know what's gonna happen," she said.
Authorities say there were surveillance cameras at this Subway but have yet to say if those cameras captured images helpful to the investigation.
Anyone with information in this case is urged to contact the HPD Homicide Division at 713-308-3600 or Crime Stoppers at 713-222-TIPS.
The restaurant is not open for business today. It is expected to reopen Thursday morning.
