Police: Woman beheaded at Oklahoma workplace

"Yes, she was beheaded," Lewis told The Associated Press before a Friday news conference.
While questioning the suspect's co-workers, investigators learned he had recently started trying to convert several employees to Islam, Lewis said. Moore police have asked the FBI to aid in the investigation and look into the man's background because of the nature of the attack, Lewis said.
I'm sure there will be much to follow about this apparent lone wolf attack. There is an element of psychology that we seem to be missing, and one you have one attack, just a like a school shooting, there will likely be others.
