"The FBI has investigated multiple theories, including whether the Border Patrol agents were ambushed or attacked or whether their injuries were as a result of an accident or any other relevant criminal activity," said FBI El Paso Special Agent in Charge Emmerson Buie Jr. "None of the more than 650 interviews completed, locations searched or evidence collected and analyzed have produced evidence that would support the existence of a scuffle, altercation, or attack."
