Honestly this list could use some trimming, you can't really have a "list of sexist incident" contain a change in the way blocking works on Twitter (http://geekfeminism.wikia.com/wiki/Twitter_Blockgate)! At least, you can't if you want people to take the list seriously...
I don't know of any killings, but there have been a number of (high profile) sexual assaults at tech conferences - see http://geekfeminism.wikia.com/wiki/Timeline_of_incidents
My friends say it's a regular (and sometimes terrifying) occurrence at some conferences. And I believe them.
