A woman was beheaded recently for posting details on a social networking site about a drug cartel.  The people that killed her found out about her true identity.  Her head was placed on a large stone piling nearby.  This action is similar in the Tudor monarchy when they would place th head of an executed person on the tower bridge.

What fascinates me is this....the police and other officials cannot figure out how the drug cartel members found out about her real identity.
