Police said it happened at 8.20am at the V Stop Food Mart in the 6500 block of Homestead Road.
Investigators found the clerk in the back room with at least one gunshot wound to the right shoulder, according to Detective Kris Persad.
Police have not confirmed whether the shooting resulted from a robbery or not.
HPD officers are interviewing witnesses who were inside the store during the shooting.
Employees and customers gathered outside the gas station in the hours following the shooting.
Shakora Sharp frequently shops at the convenience store. She said she was shocked to hear the news.
“I grew up in this neighborhood, so we come here every day. John was family to us, like the other guys. Everyone is considered family,” Sharp said. “It’s just heartbreaking, honestly, to have to go through this. I know the guys, his colleagues, the manager, everyone is hurt. Even the neighborhood because we’re so family oriented.”
Detectives said the suspect remains at large.
“Whoever did it, I hope they have at least some kind of heart, some decency to surrender. It not only hurts the community, he has a family,” Sharp said.
