Mexican authorities found the wreckage of the private plane in which Mexican-American singer Jenni Rivera and six other people had been traveling, adding that there were no survivors in the Sunday morning crash.
"The information we have is that there is not a single survivor," Civil Aeronautics chief Alejandro Argudin told the Televisa television network.
He said that the Learjet 25 was found on a ranch in a community called La Colorada in the Iturbide municipality in northern Nuevo Leon state.
The plane was "destroyed, totally fragmented" and the wreckage scattered over a relatively large area.
Traveling on board the plane with Rivera were said to be Arturo Rivera, her manager; attorney Mario Macias; makeup artist Jacob Llenares, a person identified only as "Gerardo N." and pilots Miguel Perez and Alejandro Torres.
The Transportation Ministry said that the aircraft belongs to the U.S. firm Starwood Management and that an investigation had been opened into the case.
The plane took off from Monterrey's international airport at 3:15 a.m. (0915 GMT) and was reportedly headed for Toluca.
"The aircraft lost radar contact ... 61.8 miles from Monterrey," the communique added, and a search operation was launched at 4:40 a.m. (1040 GMT), "with the help of two helicopters and an airplane."
On Saturday night, Rivera offered a concert for some 15,000 fans at the Monterrey Arena, after which she boarded the aircraft.
Rivera was considered to be one of the most important female performers of Mexican regional music, having sold more than 22 million albums and being presented with six Billboard awards and three Premio Lo Nuestro awards. EFE
