The mayor of the town of Iturbide in Nuevo Leon state, Jose Antonio Gonzalez, said a plane had been located in the municipality of Los Tejocotes, but it has not been confirmed that it is the plane Jenni Rivera was travelling in.
Jorge Domene, spokesman for Nuevo Leon's government, said he didn't have any knowledge of her plane being found.
Seven people including her publicist, lawyer, makeup artist and the flight crew were believed to be aboard the U.S.-registered Learjet 25, the ministry of transportation and communication said in a statement.
Alejandro Argudin, of Mexico's civil aviation agency, said Sunday afternoon that Rivera's plane was still listed as missing.
A small plane carrying Mexican-American singer Jenni Rivera went missing early Sunday after taking off from the city of Monterrey, authorities in northern Mexico confirmed Sunday.
Jorge Domene, spokesman for the Nuevo Leon state government, told Milenio television on Sunday that the plane left Monterrey about 3:30 a.m local time after a concert there and aviation authorities lost contact with the craft about 10 minutes later. It had been scheduled to arrive in Toluca, which is located outside Mexico City, about an hour later.
Domene said a search for the plane was launched early Sunday, with helicopters from the local civilian protection agency flying over the state. He said seven people including the crew were believed to be aboard the U.S.-registered Learjet 25.
The 43-year-old who was born and raised in Long Beach, California, is known for her interpretations of Mexican regional music known as nortena and banda.
