Collins was a California Highway Patrol officer active during Day 2. He was called in as backup after sergeant Raymond Brown pulled over Miguel and Kim Bauer and discovered the body of Carla Matheson in their trunk. Collins took Miguel into his car and drove him back to the station, despite his protests of innocence. On the ride to the station, Miguel told Collins that a nuclear weapon is somewhere in Los Angeles. Collins radioed Sergeant Brown, who had heard a similar story from Kim, and speculated that it was a story the two of them had made up.
