Florida preps for execution of mentally ill killer

A man diagnosed as a paranoid schizophrenic is due to be executed in Florida in just a few days. John Errol Ferguson, 64, believes he is "Prince of God" and can speak to his dead father. He was sentenced to be killed by lethal injection after being convicted for his involvement in a group that slayed six people during a mass murder that struck Miami-Dade County in 1977. Decades down the road, however, his execution is being opposed by critics who call into question his mental state. Journalist Rania Khalek weighs in.
