EASTVALE, CALIFORNIA (February 11, 2024) – Eleanor Roosevelt High School principal Greg Anderson has been arrested for allegedly failing to report child abuse involving a teacher.

Riverside County officials are saying that the incident began with an investigation in April 2023. Investigators were looking into a report that a teacher was having an inappropriate relationship with a student.

In November, police arrested teacher Chad Costello, 44, of Anaheim on suspicion of sexual battery of a minor. The sheriff’s office looked into whether or not the proper reporting laws were followed.

After that investigation, police arrested principal Greg Anderson on suspicion of not following mandatory reporting laws. A full investigation into the actions of Chad Costello and principal Greg Anderson remains ongoing a this time.

Liability For Riverside County Student Sexual Abuse

Student sexual abuse is unfortunately very common. According to RAIN, “One in 9 girls and 1 in 20 boys under the age of 18 experience sexual abuse or assault. 82% of all victims under 18 are female. Females ages 16-19 are 4 times more likely than the general population to be victims of rape, attempted rape, or sexual assault.” The effects of child sexual abuse can be very severe and long lasting.

  • Victims of sexual abuse are 4 times more likely to become addicted to drugs.
  • Victims of sexual abuse are 4 times more likely to have PTSD as adults.
  • Victims of sexual abuse are 3 times more likely to experience major depressive episodes once they become adults.

It is illegal for teachers to engage in any type of sexual activity with students. Depending on the facts of any case, a school could be liable if  a student is sexually abused. As outlined in Virginia G. v. ABC Unified School District (1993) 15 Cal.App.4th 1848, schools can also be liable for the sexual assault of a student if teachers knew (or should have known) about that teacher’s history of sexual abuse.

 Teachers and school officials are mandated reporters and must report any reasonably suspected instance of sexual abuse. A mandated reporter who fails to report any incident of reasonably suspected child abuse or neglect is guilty of a misdemeanor under California Penal Code 11166(c). Unfortunately, teachers will often fail to report abuse out of fear of being disciplined or losing their job. It is important that certain steps are taken after any instance of teacher sexual abuse.

  • Eye witnesses should be interviewed.
  • Medical records should be preserved.
  • A police report should be created.
  • An experienced sexual abuse attorney should be contacted.

By the time any teacher is arrested for sexual abuse, there were likely dozens of red flags that were missed. Sadly, though, schools will often do everything that they can to deny responsibility if a teacher abuses a student. It is important for victims of sexual abuse to understand that they do have rights. Any person that is sexually abused by a teacher may be able to seek some measure of justice through a civil claim. A teacher sexual abuse attorney can examine the unique facts of your case and let you know what your legal options are .
