A majority of people killed by Hurricane Katrina were older residents unable or unwilling to evacuate in the rising floodwaters, according to a study of almost half the bodies recovered in Louisiana. About 60 percent of the nearly 500 victims identified so far were age 61 or older, the Louisiana Department of Health and Hospitals reported.

"The elderly were much more likely to be in hospitals and nursing homes as well as possibly homebound and not able to access transportation in order to evacuate from the storm," said agency spokesman Bob Johannessen.

More than 215 bodies out of 1,048 recovered statewide were found in or around hospitals and nursing homes, according the state. Two nursing home operators have been charged with negligent homicide in 34 deaths at one facility, and others are under investigation.
