Alyssa Broderick was a teenager who had previously attended Elgin High School; a statement from the school’s superintendent confirmed that she and Simmons had attended the school.

Both teens were athletes. Simmons had recently been recruited to play football for the University of North Texas.

“The Elgin ISD community grieves the loss of these two young, promising souls” Superintendent Dr. Jodi Duron wrote. “In response to this tragedy, the district will have counselors and trained professionals available via in-person and/or virtually to assist students, staff and families in this time of grief.”
