Overview

• Mexican federal agents executed the arrest at the Dennis DeConcini crossing in Nogales after a controlled deportation and transferred Sandra Lucía Téllez Nieves to the Hermosillo women’s prison at the judge’s disposal.
• She was convicted in 2016 for homicidal negligence and culpable injuries, with a 28‑year, 11‑month sentence later cut to five years and seven months through amparos and appeals in April 2022.
• Téllez lived as a fugitive in the United States and was held by ICE in Eloy, Arizona under a 2022 Interpol red notice, with reports indicating an asylum request was unsuccessful prior to her return.
• Families of the 2009 victims say they were not formally notified of the detention and are urging authorities to ensure full enforcement of the punishment and transparency in the case.
• The 2009 Guardería ABC fire in Hermosillo killed 49 children and injured more than 100, and investigations documented blocked emergency exits, flammable materials and inadequate fire protections at the facility.
