HOUSTON – Police are searching for a suspect who assaulted one man and shot another near a sandwich shop in Midtown early Monday.

Investigators say a gunman pistol-whipped a worker at the Jimmy Johns on McGowen and Brazos. The attempted robbery happened around 7 a.m. as the eatery prepared to open for the day.

“He came up after I unlocked the door and tried to force me inside. I don’t know, he hit me in the head with his gun then I ran off,” said Cameron Breunig, the victim.

The suspect then shot an apparent bystander across the street from the restaurant.

Police say the bystander was a witness to the robbery and shouted "call the police" before the suspect opened fire on him, shooting him in the head.

The witness collapsed in front of a nearby Walgreens on Smith at McGowen. The store was surrounded with police tape as of sunrise. Blood was visible on the ground.

The Jimmy John’s employee and the shooting victim were rushed to the hospital.

The employee was treated and released Monday afternoon.

Police said the witness who was shot was in stable condition at last check.

The search for the suspect is still underway.
