Taggart was with Lieutenant Bryce Hardin when they set up a road block to catch Jack, who was in pursuit of a suspect who killed Frank Neal. They took him back to their base at Mountain Lake, and Taggart took Jack's car. He saw the complex systems within it (used for calling CTU Denver). He managed to make it in contact with them, at which point he realised that Jack was a federal agent. Hardin apologised to Jack, who was escorted away by CTU Denver agent Anne Armstrong. Later, it was revealed that the whole MRT team were corrupt and Taggart and Hardin were responsible for Brad Oliver's death. He and Hardin were killed after Jack using a pickup truck to push their patrol car off the precipice.
