However, since the suspect had no previous arrest record, he was not included in the police database. In December 2025, Austin detectives were notified of two incidents in which a man shot two women in separate attacks weeks apart. Authorities later received a tip that the attacker was Benítez-González and that he was trying to sell firearms in an attempt to escape the United States.
