COCC Sociologist Del Cornutt says often people who feel marginalzied are behind thse devastating events.

Cornutt says these gunmen often feel alone and are not part of a group.  "They feel like a cork in a sea.  The term tossed around is anomic, which means without any rules , no guidance.  And in order to get some reocgnition, they turn to thse atrocious kinds of acts."

The FBI just revealed that the army veteran and white supremacist who killed six people at a Milwaukee temple on Sunday died from a self inflicted gunshot wound to the head.

The gunman played in several white supremacist rock bands and was a member of the skinhead organization, the Hammerskins.
