Trackdown: Help find Marco Clewis' killer

On October 24 around 12:30 a.m., Marco Clewis was murdered in his home, and detectives want to know why. His brother, Burris, bolted out of his house across the street shortly after to try and help.

The two brothers died within minutes of each other. One was shot to death while the other was killed in a car crash chasing the shooter.

“These guys, the Clewis family, they are well known in this area,” said Detective Tanya McDaniel. “And people loved both of them.”

But not everyone.

Marco lived in his house at 4215 Copeland in South Dallas. His brother, Burris, lived straight across the street.

After hearing the gunshots from Marco’s house, Burris went outside and saw the suspect’s vehicle and immediately went after who had just shot his brother.

“The suspects are in a white small vehicle, a four-door car that’s possibly a white Nissan Sentra,” McDaniel explained. “He's after this car. They're speeding.”

There is video from one of the Dallas Police Department cameras that are set up at certain intersections throughout the city.

The car and the SUV driven by Burris were caught crisscrossing South Dallas streets. What's not caught on tape was the crash that killed Burris along on Elsie Faye Heggins Street and Second Avenue.

“I do know that he also was getting shot at,” McDaniel said. “There were defects in his windshield to indicate that he also was getting shot at while chasing the suspects.”

McDaniel calls it a double tragedy.

“Very sad,” she said. “I mean, you have two sons that took care of their mother gone at one time.”

A reward is being offered. Anyone with information is urged to call Crime Stopper at (214) 373-8477.
