Eastvale – After an Eleanor Roosevelt High School (ERHS) teacher was arrested in 2023, an investigation determined the ERHS Principal allegedly didn’t follow mandated reporting laws and he was arrested in February 2024.

In April 2023, investigators with the Riverside County Sheriff’s Office, Special Victims Unit, received a report that a teacher was allegedly having inappropriate contact with students. The teacher was identified as Chad Costello, 44-year-old resident of Anaheim. Costello was hired in August 2021 as the ERHS Theater teacher but was placed on administrative leave in April 2023 when the allegations came to light. He was arrested on November 16 in the city of Anaheim and was booked into the Robert Presley Detention Center. According to Riverside County jail records, he is being charged with two felony counts of sexual battery, four misdemeanor counts of sexual battery for purposes of arousal, and four counts of misdemeanor annoying or molesting a child.

“An additional investigation was launched to determine if mandated reporting laws were followed correctly,” according to a Riverside County Sheriff’s Department (RCSD) news release. During the investigation, evidence was obtained that determined laws were not properly followed. “The investigation revealed that a school administrator, Greg Anderson, a 44-year-old resident of Eastvale, failed to report incidents to law enforcement,” according to the news release. Anderson was arrested on February 9 in the city of Eastvale, and he was booked into the Robert Presley Detention Center. Anderson was placed on administrative leave, according to a Corona-Norco Unified School District statement.
