Thread:Comments:Gunman commits suicide at University of Texas/How did he make it all the way up to the 6th floor of the Perry-Castaneda library ?/reply

I don't think that guard is armed, also the library is not very busy at 8:20am.

I think the real question is what he and the police did in the 20 or so minutes between climbing the stairs to the 6th floor and ending his life. Supposedly police gave chase but did they have him pinned down for 20 minutes? Did they negotiate with him?
