I just called (225) 389-5247 again. I reached an officer who said that he had no information on the arrestees. He said that they were held at the jail which is run by the Sheriff's Dept. He gave me the number (225) 358-4009 to call, but it was disconnected.
When I persisted with the officer saying that I was concerned about these people being arrested, the officer said that those arrested, "will be fine" and asked if I was a member of the family. I responded that I was concerned about American citizens being arrested. He said, "American citizens are arrested all over the country all the time." I responded that generally we are told what their charges are.
He again reiterated that they have no information and I should try the Sheriff. When I responded that the Sheriff's line is disconnected, he said that is probably because of all the "crazy calls."
When I asked his name, he hung up on me, despite calling me "Mr. Klein" several times without my giving his name (most likely due to caller id).
