SALT LAKE CITY (AP) — A sex offender with a stolen boarding pass got through airport security in Salt Lake City and checked in at a gate for a flight to California before he was caught earlier this month, authorities have disclosed. The day after the security breach in Utah, TSA officials in Washington announced enhanced security for certain inbound international flights in response to an explosion aboard a Russian passenger jet after takeoff from Egypt. Southwest spokeswoman Brandy King says the Dallas-based airline relies on TSA to verify boarding passes and identification, and the airline's systems worked properly by flagging a boarding pass that already had been scanned and identifying a passenger who didn't belong on the flight.
