El Cajon has a total of 40 cameras across the city attached to light and traffic poles and this camera on North Mollison Rd was able to capture the vehicle driven by the man that police say shot three people, giving officers a vital clue that led to his arrest. El Cajon police are crediting the use of technology in helping them catch the man they say opened fire at a dentist office Thursday evening. After the deadly shooting broke out, a tip from a witness led police to believe the suspected gunman had taken off in a white U-Haul. El Cajon police were able to use the city's Flock license plate readers to get a picture of the truck with Arizona plates.
