An undercover sheriff’s deputy shot and killed a suspect hiding in a tow truck on a car dealership lot following a short foot chase in National City early Friday afternoon, authorities said. The deputy suffered cuts from broken glass, but the wounds are minor and he is expected to be OK, San Diego homicide police Lt. Lou Maggi said. San Diego police are handling the investigation under a countywide protocol designed to keep agencies from investigating themselves. A sheriff’s official said the encounter happened just before 1:40 p.m. on Mile of Cars Way near Hoover Avenue, just east of Interstate 5. According to Maggi, sheriff’s deputies were in the area conducting some sort of operation when they tried to stop a white four-door Acura on Mile of Cars Way. The car stopped. A man in the front passenger’s seat bolted, running into the nearby car dealership, Maggi said. Two other people in the Acura — a man and a woman — stayed in the car and were arrested.

Maggi said a witness pointed one of the deputies and a National City police officer to a lot at the back of the dealership, and said the man they were looking for was hiding inside a tow truck. “As they approach that tow truck, an officer-involved shooting occurs,” Maggi said. “We don’t really have the details yet on what led to that.” The deputy opened fire, Maggi said. The National City officer did not shoot. The lieutenant did not know whether the suspect opened fire. The shooting was captured on body-worn camera, he said. “There was a gun found nearby him,” Maggi said. “It looks like that gun was jammed. We’re going to be processing that gun. I can’t tell if it’s a real firearm or replica.” He said the deputy who opened fire was likely injured by “glass from a window exploding.” Maggi said the two people in the Acura were arrested on a narcotics-related charge. The lieutenant said he believed drugs were found inside the car. Nick O’Neil, a physical therapist who works near the site, said there was suddenly “a lot of commotion,” a lot of sirens and a lot of law enforcement officers on scene. “Between like the moment where people heard the gunshots to then all the cruisers being here, (it) felt like just seconds. Honestly, it was very quick,” O’Neil said National City police issued an advisory asking people to avoid the area, citing the investigation and road closure.
