A teacher at Hart Elementary School in Austin ISD did not return to his class after leaving for an errand. Roberto López Falcón told his students he would be back on Thursday, but he was detained by US Immigration the next day. He was supposed to discuss the students' likes and dislikes about the day upon his return, but that never happened.

López Falcón's absence lasted the entire school year. Further details about López Falcón's situation are available from the Austin Current.
