Five people were killed when their small plane crashed and burned near the Colorado River, authorities said. The Cessna 172, registered in Palm Desert, took off from a desert airfield near Lake Havasu, San Bernardino County Sheriff's Sgt. Jim Singley said. Several fisherman said they saw the craft circle the area and then heard it crash. Three men and two women were confirmed dead at the scene, coroner's spokesman Frank Lee said. The bodies could not be immediately identified, he said.
