Sloan is a cop who works with Lucas at the police department. Sloan apparently does not have a first name, at least not one he wants people to know, because even his wife claims not to know it. Sloan does a lot of the background work, looking at criminal histories of suspects and possible lovers Stephanie Bekker may have had. After Cassie is killed, Sloan takes Lucas home and stays with him all night to protect him from his own depression and the possibility of suicide. Later, when Michael Bekker is arrested, Sloan is with Lucas and stops him from beating Bekker.
