State prosecutors say the pit was discovered in February 2016 near the northern city of Monterrey, but in the year since then investigators have been painstakingly analysing the fragments and teeth to see how many people were buried there and who they were.
On Sunday, the prosecutors' office said 24 sets of remains were identified through DNA testing. Thirty-two others have not been identified. Some of the remains belonged to people who had been reported missing since 2010.
