MFH has been around FR for years.
Even the mayor of N.O. has for 2 days made mention of bodies floating in the water, but emphasized that they are focusing on rescuing the living. I saw him say this in interviews on local (WDSU & WWL) Gulf media outlets. It is obvious there are many, many more dead than have yet been tallied or "announced".
It is more than rumor. Sadly.
I heard a news report on the local hi-watt AM news station (WSB) this moring that search and rescue crews were not recovering floating bodies, that they were concentrating on rescuing the living.
