Video shows gunman chase man down sidewalk before deadly shooting in southeast Houston

HOUSTON, Texas (KTRK) -- Investigators are searching for a gunman accused of shooting and killing a man while walking along a sidewalk in southeast Houston.

Houston police tweeted surveillance video of a suspect seen shooting the victim at 7126 Woodridge Drive, near Evergreen.

The shooting happened around 9:15 p.m. on Saturday, police said.

A neighbor tells ABC13 he witnessed the shooting.

"The guy fell off on the ground and he stood up and tried to run away, but the guy came out of the car, followed him and continued shooting in front of the white car," the neighbor said.

In the surveillance video, the man can be seen walking along the sidewalk when a sedan slows down next to him.

The man takes off running, and that's when the suspect got out of the car, chased after him, and fired his weapon multiple times.

The neighbor said he heard nine gunshots.

"We're still trying to figure out why," he said. "We don't have any idea why that happened, because the guy was just walking."

The victim then ran toward a house to call for help but collapsed, police said. He was found lying in the front yard and was pronounced dead at the scene.

"I just heard the gunshots and when I came out a man was there, I guess he was dead," said Robert Martinez, who was inside his home with his children.

The victim died in Martinez's front yard.

Police described the suspect seen in the video as a tall, slender Black man. He reportedly fled the scene in a gold sedan, traveling eastbound on Woodridge.

Investigators initially said two suspects exited the vehicle, one from the passenger side and one from the back.

Police described the victim as a 58-year-old man.
