- "Sweet... mother... of... shit!"
- — Deputy Kirkman
He appears during The Paleto Score as he is the first unit to respond to the Blaine County Savings Bank alarm, arriving in a Sheriff Cruiser with another officer to check what happens with the alarm, and when he realizes there is a real robbery he takes cover behind the car (frightened by Trevor Philips) and calls for support with the radio.
Later, with all the reinforcements covering the entrance, he speaks through a Loudhailer warning the robbers and trying to reach an agreement. However, as Trevor and the crew appear with the Juggernaut suits and the Minigun he gets shocked and says his last words: Sweet...mother of...shit!. He can be killed during the mission but it is not required.
Whether he is killed in the Paleto Score or not, random NPC models with the Kirkman name badge will continue to spawn at Paleto Bay Sheriff's Office and the female deputy at Sandy Shores Sheriff's Station can also spawn as "Kirkman".
