It’s interesting the police chief calls it workplace violence. My take on what I've read is that Le was not remotely an elitist but the exact opposite-- the type of girl who was always smiling and nice to everyone, even “lowly” lab technicians (aka janitors, in that Clark cleaned cages). Given Clark's membership in the Asian Club in high school, he was likely attracted to her and harbored certain related fantasies of which she either had *no* knowledge or simply chose to ignore as many popular women often do lest they do anything that would encourage said person. Given Clark's girlfriend's need to deny rumors he was having an affair, he likely talked about Le outside of work, indicating an obsession. 
  When it got close to Le's wedding day, which Clark probably considered the ultimate rejection, he probably confronted her about making a bad choice. As this is the last thing you want to hear days before your wedding, and being on edge anyhow, Le probably got emotional and wanted to leave the room, he wouldn’t let her (“hear me out”), she started to yell, he tried to silence her, she got physical in defense, he got more physical. In other words, things escalated to murder. 
  He couldn’t leave her body there ready to be discovered because it would surely implicate him, so he frantically looked for a place to hide her. That would explain the reports of him entering all sorts of rooms where he should not have been, as opposed to a guy who premeditated the whole thing.
