And Keetch’s family isn’t alone.

Megan Matteson, who also lives in Ladera Ranch, lost her son Brody in March after battling Ewing sarcoma and treatment-related leukemia, the New York Post reported.

“To have three families that just contacted me right away after Brody was diagnosed was helpful but scary at the same time,” Matteson told the New York Post.

Earlier this week, Bond Legal announced it had launched an investigation into the cases, saying it is seeking information from familiar whose children lived in or regularly visited the Ladera Ranch community.

“The concentration of cases in a single community is deeply troubling, especially to those who live there,” Bond Legal Managing Partner Candice Bond told the New York Post.
