man Tuesday was fatally shot by a Houston Police Department officer after the man allegedly rammed the officer's SUV and then physically assaulted him in the parking lot of a Family Dollar in southeast Houston, police said. The man was shot once in the upper chest and died at a hospital, police said. Neither he nor the officer had been immediately identified. The shooting happened around 2:35 p.m. in a parking lot near the intersection of Martin Luther King Boulevard and East Orem. Shortly before the shooting, the officer — who had been in a marked police SUV — spotted a black Honda Civic in the parking lot of the store, said Houston Police Department Executive Assistant Chief Ban Tien. The license plates on the Honda matched a car that had been reported stolen in downtown Houston after a strong-arm robbery Tuesday morning, Tien said. The officer parked behind the car, got out, approached the vehicle and found a man in the driver’s side seat, Tien said. The man refused to get out of the car and tried to back out of his spot, ramming the police SUV, according to Tien. After that, the man got out of the car and approached the officer, Tien said. A struggle followed. The man at one point straddled the officer, Tien said. The officer's Taser and body camera were knocked off his body, Tien said. It was at that point the officer drew his duty weapon and fired the handgun once, Tien said. The man was taken to a hospital, where he died. He had not been identified but police described him as a Black man in his 40s. The medical examiner's office was expected to conduct an autopsy. The man was not believed to have been armed when he was shot, Tien said. He was believed to have two felony warrants, Tien said, but it was not clear whether police had run his information prior to the initial altercation. The officer has been with the police department for 7 years and is a member of the department's gang unit, Tien said. He suffered “bruises and bumps” in the struggle, Tien said. The officer was placed on administrative duty following the shooting, which is customary after shooting by a law enforcement officer. "I want to emphasize that this is just a preliminary investigation," Tien said. "What we have is a snapshot view of what happened and it's going to take a lengthy investigation." There was at least one witness to the shooting: a woman who was with the shooting victim at store. Tien said the woman approached the officer during the struggle but didn't touch him. Police had been attempting to collect video evidence at the scene, but Tien said there were limits to what was immediately available. The store didn't have functional cameras and neither did the officer's SUV, Tien said.
