New Orleans ? A security guard at a FEMA trailer park was shot to death Monday in the latest violence to rack the city still struggling to recover from Hurricane Katrina, police said.

The shooting, around 5:15 a.m., was at a trailer park in Gentilly, a section of the city that flooded during Katrina. A few hours earlier, another man was shot and killed near the Guste public housing complex.

The latest violence brought the number of homicides in the city this year to 34. Last year, New Orleans counted 161.

Steven Nicholas, a chief in the police department, said the security guard was about 50 years old. A motive for the shooting had not been established, although he said “robbery does not appear to be a motive.”
