Monterrey, Mexico (CNN) - Millions of fans on both sides of the U.S.-Mexico border are mourning the death of Jenni Rivera, whose performances of soulful ballads sold out concert halls and made the singer a household name for many.
Crews were set to resume the search Monday for Rivera's remains amid the wreckage of a plane that crashed in the remote, mountainous area in northern Mexico on Sunday.
"The plane was totally destroyed. ... It is a great tragedy," her brother, Gustavo Rivera, told CNN en Español.
Six others were killed, including the singer's publicist, lawyer and makeup artists, he said. Family members were planning to travel to Mexico on Monday as investigators work to determine what caused the crash.
The small Learjet plane that Rivera was flying in was 43 years old, the state-run Notimex news agency reported, citing the director of civil aviation for Mexico's Transportation Ministry.
Collecting evidence at the scene could take up to 10 days, Alejandro Argudin said, according to Notimex. The wreckage, which includes personal items that belonged to the singer, was spread out over an area that spans up to 300 meters (more than 320 yards), officials said.
The U.S. National Transportation Safety Board said Monday that it was dispatching a team to help with the investigation.
Meanwhile, fans, family members and entertainers said they were devastated to learn of Rivera's death.
"The world rarely sees someone who has had such a profound impact on so many," Universal Music Group said in a statement. "From her incredibly versatile talent to the way she embraced her fans around the world, Jenni was simply incomparable. "FULL STORY
