The body of a missing Mexico teen from Nuevo Leon state was discovered submerged in a cistern on the premises of a motel near where she was last seen alive, authorities said on Friday.

Debanhi Escobar, an 18-year-old law student, went missing on April 9 as part of a wave of female disappearances in Nuevo Leon’s capital Monterrey, sparking protests and increasing international scrutiny of gender violence in Mexico.

Twenty-six women and girls have disappeared in Nuevo Leon this year, and five more have been found dead after being reported missing.

“The body found is Debanhi’s, and the cause of death is a profound contusion to the skull,” state attorney general Gustavo Guerrero said in a Facebook live video. All lines of investigation are open, he said.

Guerrero’s comments came as hundreds of women blocked a highway in downtown Monterrey, paralyzing traffic, demanding an end to gender violence.
