Beheading in the United States has left the world baffled at how radicalization of youths by clerics is increasingly becoming a threat to global security.
Alton Nolen stabbed a 54 year old woman before beheading her inside a foods factory in Oklahoma, the city where Tim-McVeigh conducted a terror attack years ago.
Alton Nolen beheaded Colleen Hufford, a workmate at the factory before attacking Traci Johnson another workmate.
The owner of the factory managed to shoot the assailant before he managed to behead Traci Johnson.
Nolen had radicalized and converted to Islam before he committed the crime
