The investigation began on Feb. 15, when authorities were contacted by one of the men, who told a Montebello police lieutenant he wanted to get his relationship with the teacher off his chest. That allegation triggered an investigation that led to the second victim.

Cortez was placed on leave following her arrest. She is free on bail.
