An innocent bystander was shot and killed on Sunday morning, Jan. 12, after an altercation at a southwest Houston convenience store, police said.

A man with a gun entered a gas station convenience store around 4:10 a.m., police said. The gunman then approached the store clerk and forced him to open the secured area to commit the robbery.

And while the clerk tried to fight back with the gunman, a bystander, who often volunteers at the store, Elwin Oubre, also tried to help the clerk. But Oubre was shot in the chest and killed.

“He tried to get the money and was pushing me, and I was pushing him back,” said the store clerk, who didn’t want to be identified. “(The gunman) dropped the gun accidentally, so (Oubre) tried to pick up the gun, or I don’t know what he was trying to do, but he was trying to help me.”

The suspect then fled the scene.

Oubre was described as the kind of man who would do anything to help out, KPRC2 reported.

“He did save my life, but I can’t thank him enough you know,” the clerk said. “I’m really glad that he helped me. I feel bad for him at the same time.”

The suspect also was described as a “young-looking” Hispanic male wearing a gray hoodie with a yellow logo, dark pants with rips at the knees and white sneakers, according to Chron.com.
