Authorities in Mexico have begun performing Dna tests to identify human remains found in what is believed to be Jenni Rivera's plane crash.

The Latin superstar and six others who were on-board the private Learjet 25 have been presumed dead after wreckage was found scattered in Nuevo Leon state in northern Mexico on Sunday (09Dec12).

Experts transferred remains found in the debris to a hospital in nearby Monterrey, and investigators are now examining Dna samples in order to give relatives definitive confirmation of their loved ones' deaths.

According to the Associated Press, the U.S. National Transportation Safety Board has sent a team to Mexico to help with the probe.

Officials have told the Mexican media it could take days to confirm whether the remains are Rivera's and to piece together why the plane crashed soon after takeoff.
