Federal regulators repeatedly granted appeals to remove Camp Mystic’s buildings from their 100-year flood map, as the camp operated and expanded in a dangerous flood plain in the years before rushing waters swept away children and counselors.

Abby, who was 8 years old and a student at Casis Elementary, is the third child from Austin confirmed to have died in the July 4 flood. At least 96 people — 60 adults and 36 children — have died and more than 160 are still missing in Kerr County.
