A San Antonio police detective received a 30-day suspension over allegations that he secured help from another law enforcement agency using false pretenses and sent an online message to an ex-girlfriend urging her to kill herself, city records show. The San Antonio Police Department suspended Detective Arthur F. Lopez in June following an internal affairs investigation into his conduct, according to a disciplinary filing. The probe unfolded after Schertz police issued a criminal trespass warning to the 17-year force veteran.
