MONTERREY, Mexico - U.S. authorities confirmed Monday that Jenni Rivera, a U.S.-born singer whose soulful voice and openness about her personal troubles made her a Mexican-American superstar, was killed in a plane crash in northern Mexico.
The National Transportation Safety Board said it was sending a team to help investigate the crash, and the board was told by Mexican authorities that Rivera had died in Sunday's crash.
Rivera's relatives in the U.S. already had few doubts that she was on the Learjet 25 that disintegrated on impact Sunday in rugged territory near the town of Iturbide in the Sierra Madre Oriental in Nuevo Leon state.
"My son Lupillo told me that effectively it was Jenni's plane that crashed and that everyone on board died," her father, Pedro Rivera, told dozens of reporters gathered in front of his Los Angeles-area home. "I believe my daughter's body is unrecognizable."
He said that his son would fly to Monterrey Monday or Tuesday.
Alejandro Argudin, of Mexico's civil aviation agency, said Monday it would take at least 10 days to have a preliminary report on what happened to the plane.
"We're in the process of picking up the fragments and we have to find all the parts," Argudin told reporters. "Depending on weather conditions it would take us at least 10 days to have a first report and many more days to have a report by experts."
The Learjet 25, number N345MC, took off from Monterrey at 3:30 a.m. local time en route to Toluca, outside Mexico City, and was reported missing about 10 minutes later. It was registered to Starwood Management of Las Vegas, Nevada, according to FAA records. It was built in 1969 and had a current registration through 2015.
According to the National Transportation Safety Board, the twin-turbojet was substantially damaged in a 2005 landing mishap at Amarillo International Airport in Texas. It hit a runway distance marker after losing directional control. There were four aboard but no injuries. It was registered to a company in Houston, Texas, as the time.
Messages of condolence poured in to the Rivera family from musicians and celebrities.
Mexican songstress and actress Lucero wrote on her Twitter account: "What terrible news! Rest in peace ... My deepest condolences for her family and friends." Rivera's colleague on the Mexican show "The Voice of Mexico," pop star Paulina Rubio, said on her Twitter account: "My friend! Why? There is no consolation. God, please help me!"
Born in Los Angeles, California, Rivera was at the peak of her career as perhaps the most successful female singer in grupero, a male-dominated regional style influenced by the norteno, banda and ranchero styles.
A 43-year-old mother of five children and grandmother of two, the woman known as the "Diva de la Banda" was known for frank talk about her struggles to give a good life to her children despite a series of setbacks.
She was recently divorced from her third husband, was once detained at a Mexico City airport with tens of thousands of dollars in cash, and she publicly apologized after her brother assaulted a drunken fan who verbally attacked her in 2011.
Her openness about her personal troubles endeared her to millions in the U.S. and Mexico.
"I am the same as the public, as my fans," she told The Associated Press in an interview last March.
Rivera sold 15 million records, and recently won two Billboard Mexican Music Awards: Female Artist of the Year and Banda Album of the Year for "Joyas Prestadas: Banda." She was nominated for Latin Grammys in 2002, 2008 and 2011.
Transportation and Communications Minister Gerardo Ruiz Esparza said the impact of the crash was so powerful that the remains of the plane "are scattered over an area of 250 to 300 meters."
"There is nothing recognizable, neither material nor human" in the wreckage, he said.
A mangled California driver's license with Rivera's name and picture was found in the crash site debris.
Also aboard the plane were Rivera's publicist, Arturo Rivera, her makeup artist, Jacob Yebale, two friends, one named Mario Macias and another who was only identified as Gerardo, and the two pilots, said Mexico's Communications and Transportation Department in a statement.
Though drug trafficking was the theme of some of her songs, she was not considered a singer of "narco corridos," or ballads glorifying drug lords like other group. She was better known for singing about her troubles in love and disdain for men.
Her parents were Mexicans who had migrated to the United States. Two of her five brothers, Lupillo and JuanRivera, are also well-known singers of grupero music.
She studied business administration and formally debuted on the music scene in 1995 with the release of her album "Chacalosa". Due to its success, she recorded two more independent albums, "We Are Rivera" and "Farewell to Selena," a tribute album to slain singer Selena that helped expand her following.
At the end of the 1990s, Rivera was signed by Sony Music and released two more albums. But widespread success came for her when she joined Fonovisa and released her 2005 album titled "Partier, Rebellious and Daring."
Besides being a singer, she is also a businesswoman and actress, appearing in the indie film Filly Brown, which was shown at the Sundance Film Festival, as the incarcerated mother of Filly Brown.
She was filming the third season of "I love Jenni," which followed her as she shared special moments with her children and as she toured through Mexico and the United States. She also has the reality shows: "Jenni RiveraPresents: Chiquis and Raq-C" and her daughter's "Chiquis 'n Control."
In 2009, she was detained at the Mexico City airport when she declared $20,000 in cash but was really carrying $52,167. She was taken into custody. She said it was an innocent mistake and authorities gave her the benefit of the doubt and released her.
In 2011, her brother Juan assaulted a drunken fan at a popular fair in Guanajuato. In the face of heavy criticism among her fans and on social networks, Rivera publicly apologized for the incident during a concert in Mexico City, telling her fans: "Thank you for accepting me as I am, with my virtues and defects."
After a concert in Monterrey Saturday night, she gave a press conference during which she spoke of her emotional state following her recent divorce from former Major League Baseball pitcher Esteban Loaiza.
"I can't get caught up in the negative because that destroys you. Perhaps trying to move away from my problems and focus on the positive is the best I can do. I am a woman like any other and ugly things happen to me like any other woman," she said Saturday night. "The number of times I have fallen down is the number of times I have gotten up."
Rivera had announced in October that she was divorcing Loaiza after two years of marriage.
There have been several high-profile crashes involving Learjets, known as swift, longer-distance passenger aircraft popular with corporate executives, entertainers and government officials.
A Learjet carrying pro-golfer Payne Stewart and five others crashed in northeastern South Dakota in 1999. Investigators said the plane lost cabin pressure and all on board died after losing consciousness for lack of oxygen. The aircraft flew for several hours on autopilot before running out of fuel and crashing in a corn field.
Former Blink 182 drummer Travis Barker was severely injured in a 2008 Learjet crash in South Carolina that killed four people.
That same year, a Learjet slammed into rush-hour traffic in a posh Mexico City neighborhood, killing Mexico's No. 2 government official, Interior Secretary Juan Camilo Mourino, and eight others on the plane, plus five people on the ground.
