MONTERREY, Mexico -- Mexican authorities are performing DNA tests on remains believed to be those of singer Jenni Rivera and six other people who died when her plane went down in northern Mexico early Sunday.
Human remains found in the wreckage have been moved to a hospital in Monterrey, the closest major city to the crash.
Investigators say it will take days to piece together the wreckage of the plane and find out why it went down.
Authorities have started looking into the history of the plane's owner, Starwood Management of Las Vegas. Another of its planes was seized in September by the U.S. Drug Enforcement Administration.
Rivera, who was born in California, became a superstar in Mexican music. She was also known for talking openly about her struggles to give a good life to her children despite a series of setbacks.
She recently filed for divorce from her third husband, former Major League pitcher Esteban Loaiza (loh-EYE'-zuh).
Her fans have been setting up shrines to her in cities in Mexico and in California.
