AP – Mexican authorities did not notify families of 43 college students who disappeared after a clash with police that some of the young men’s clothing was discovered shortly after they went missing, a group of independent experts said.

The Interdisciplinary Group of Independent Experts also reported that security videos containing visual evidence might have been destroyed.

The group said it will issue a final report on Sept. 6, but wants its investigative mandate extended beyond that date.
