WBAP/KLIF – The search for a Mansfield teenager who’s missing in the Gulf of Mexico has been suspended by the Coast Guard. 16 year old Carlos Perez disappeared while on a school trip from Mansfield’s Lake Ridge High School. He was last seen Friday morning, swimming in rough surf with a group of other students near Bob Hall Pier on South Padre Island. Two days of searching turned up nothing, and the Coast Guard says it has reluctantly concluded there’s no point to continuing.
