Police have released surveillance footage from a nearby DART station of a person of interest in a fatal shooting at Sherlock's Pub and Grill.
Dallas police have released surveillance video of a man they believe may be involved in the shooting death of a Good Samaritan outside of a popular Dallas pub last week.
Donald Morrow, 36, was shot and killed while trying to stop a robbery in the parking lot of Sherlock’s Pub and Grill early Thursday morning.
"I've just lost my only son," said his father, Don Morrow Sr. "I put my only son to rest today, and I’m doing terrible."
He and his wife, Margie, had just returned from their son's funeral when they learned Dallas police had released surveillance video of a person of interest in the case.
"The man has no idea what he took away," Margie Morrow said.
The surveillance video of the person of interest was caught on camera at a nearby Dallas Area Rapid Transit rail station.
"If we don't get this person off the street, your son, your daughter, your granddaughter could be next, and that doesn't need to happen to anyone else," Don Morrow said.
The Morrows said Dallas police detectives called them Thursday night, saying they had identified a suspect and issued a warrant for his arrest. But it never materialized, the Morrows said.
"Don't call a grieving family and tell them you have a suspect when you don't," Don Morrow said. "That's the worst thing you can do."
Police said they believe the man in the surveillance video may have been involved in several other crimes on the same day.
Oak Farms Dairy is offering a $10,000 reward for information that leads to an arrest in the case.
