Armed guards a fixture outside pot farm before 4 were slain

Armed guards were a fixture outside the marijuana growing operation in rural Oklahoma where four people were slain execution-style.

The mail carrier "was met with guns pretty much all the time,” Jack Quirk, the owner of the local paper, All About Hennessey, told The Associated Press on Wednesday. “Why are there guards anyway? You know, if it’s a legit farm, what’s the deal?"

The Oklahoma State Bureau of Investigation announced Tuesday that the suspect in the weekend killings, Wu Chen, was taken into custody by Miami Beach police and brought to the Miami-Dade County Detention Center.

He was arrested “after a car tag reader flagged (the) vehicle he was driving,” the bureau said. The suspect will be charged with murder and shooting with intent to kill and faces extradition to Oklahoma. No attorney has been assigned to him yet.
