Katrina Victims Blamed for Houston Crime

Katrina sent a lot of bad guys to Texas, as Houston is finding out.

Houston took in 150,000 evacuees - the most of any U.S. city - after Katrina struck on Aug. 29. Houston police believe the evacuees are partly responsible for a nearly 17.5 percent increase in homicides so far this year over the same period in 2005.

About 21 percent of Houston's 232 homicides through July 25 involved an evacuee as either a suspect or a victim, according to police, who attribute much of the bloodshed to fighting among rival New Orleans gang members.
