According to authorities, Hansen was arrested on suspicion of statutory rape, oral copulation of a minor and other sex-related crimes with multiple victims.
The investigation into the alleged sexual encounters began on June 18, after the Corona-Norco Unified School District alerted the Corona Police Department of a possible inappropriate relationship between Hansen and a former student.
During the investigation, detectives identified multiple victims, under the age of 18 years, who have had sexual contact with the teacher, while on school grounds. On June 20, 2013, two search warrants were served in regard to this case; one in the City of Corona and the other in the County of Riverside.
This is an ongoing investigation and there may be other victims. The police are asking for parents of male students who attend Centennial High School to speak with their children about any contact they may have had with Hansen.
If anyone has information on this case, please contact Detective Mario Hernandez of the Corona Police Department at (951) 279-3659.
