Overview
- First Assistant U.S. Attorney Bill Essayli asked the EPA on Thursday to investigate reports that multiple children in Ladera Ranch have been diagnosed with rare cancers and to determine whether federal laws may have been violated.
- Local reporting first identified six Ewing sarcoma cases and later described about a dozen rare pediatric cancer diagnoses in Ladera Ranch and nearby Orange County communities.
- Families say pesticides and other landscaping chemicals could be a cause after serious harms including the March death of 17‑year‑old Brody Matteson and the amputation of 18‑year‑old Haven Keetch following synovial sarcoma.
- State and county health agencies and the California Cancer Registry are reviewing updated cancer data and caution that a small-area rise in cases does not by itself prove a common cause.
- If the EPA or other agencies identify environmental factors the findings could prompt enforcement, rule review, or further scientific study, though legal claims will require strong medical and scientific evidence and investigations can take weeks to months.
