Mexican authorities were performing DNA tests Tuesday on remains believed to belong to Mexican-American music superstar Jenni Rivera and six other people killed when her plane went down in northern Mexico.
Investigators said it would take days to piece together the wreckage of the plane carrying Rivera and find out why it went down.
Authorities, meanwhile, began 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 in McAllen, Texas.
The U.S. National Transportation Safety Board said it was sending a team to help investigate the crash of the Learjet 25, which disintegrated on impact Sunday with seven people aboard in rugged terrain in Nuevo Leon state in northern Mexico.
