Cpt. Jason Waldrip with the Kerr County Sheriff's Office says the department has coordinated with a local construction company, the Texas Department of Public Safety and a team from Acuña, in the Mexican state of Coahuila, to locate the missing.
"We have spotters on the ground, so as materials are being removed, we are looking for anything of a sign of a person that may be within this material," Waldrip said.
Heavy equipment is being used to remove debris build up.
He asks anyone in Kerrville to avoid areas where excavators are working.
