Yes, so far as we know this bears some similarity to the Xerox killings that left seven men dead.

What we must consider is that workplace violence is rarely "senseless" no matter how much some are tempted to label it as such.

Let me say now that murder is in no way justified, no matter if the perpetrator has been victimized by bullying, being marginalized by other employees or management, or has even been outright abused or been the victim of theft by coworkers or management.  You may recall that very much like today's killings, Byran Uyesugi had ample opportunity to murder at least one other Xerox employee who, if memory serves, he happened to intercept on a stairway.  This in itself indicates that only specific people were targeted, and this was not at all a case of a man gone berserk.

In the years since, I've met face-to-face with several friends and family members of Uyesugi's victims.  About half understood perfectly well why his victims were chosen.  And now I'll say no more.
