The boat was carrying more than 40 people when it capsized.  Harry Edwards, a spokesman for the U.S. State Department, said Tuesday that so far 19 American passengers have been rescued. But the search continues for seven more American passengers, he said.  U.S. authorities identified the killed American as Leslie Yee. Her city of residence was not immediately available, authorities said.  "The State Department expresses its condolences to the victim's family and remains in contact with the survivors and families of the missing," the agency said in a statement.  There were conflicting numbers on how many people were on the boat when it sank. Mexican authorities counted 43 passengers and crew, while the Coast Guard put the number at 44.  One of the surviving tourists is Charles Gibson, the chief of police services at Contra Costa Community College District in California. Gibson is an avid fisherman and has participated in the same deep sea fishing trip several times, said Contra Costa Community College spokesman Tim Leong.  Gibson's family has been in contact with him but Leong declined further comment about the circumstances of the incident pending Gibson's return from Mexico.  According to the Contra Costa Community College website, Gibson served in the U.S. Navy where he was assigned to the USS Ranger. He served two terms in Vietnam and received the Vietnam Service Medal.  Burwell said the Americans had a C-130 aircraft on scene helping with the search, and were plotting the drift from the site of the incident. Mexican authorities also had assets aiding in the search, he said.
