SAN ANTONIO, Texas — Three people were arrested following an investigation into mail theft at an apartment complex mailbox on Gus Eckert Road, according to the San Antonio Police Department.
Police said officers responded Thursday, May 7, 2026, after receiving a call reporting mail theft at the complex. Investigators later arrested three suspects in connection with the case.
Authorities said the arrests helped prevent the theft of private information belonging to more than 10 people. Additional unrelated charges involving controlled substances and outstanding warrants were also filed against the suspects.
Police identified one of the suspects as 41-year-old Bianca Trevino, who was arrested Friday afternoon, May 8. Trevino was charged with Mail Theft, Use of Illegal License or Certificate (used to defraud), and Unlawful Conduct Involving a Mail Receptacle Key or Lock. Authorities said the latter charge is a felony involving possession or duplication of a USPS private postal key.
A second suspect, 22-year-old Ariannah Diamante Martinez, was also arrested Friday afternoon, May 8. She was charged with Mail Theft and Failure to Identify as a Fugitive with Intent to Give False Information. Police said Martinez also had an active warrant for Assault Causing Bodily Injury to a Family Member.
The third suspect, 31-year-old Elijah Karriem Davis, was arrested Saturday morning, May 9. Davis was charged with Mail Theft and Possession of a Controlled Substance PG-2 between 1 and 4 grams. Authorities said Davis also had an open warrant for Assault Family Violence, Second Offense.
Mail theft has become an increasing problem across Texas, particularly in larger cities, with thieves frequently targeting checks and personal identifying information used in identity theft and fraud schemes.
Police said criminals often use stolen or counterfeit “arrow keys,” which are master postal keys used to access mailboxes and outgoing mail collection areas. Authorities noted that losses tied to check fraud exceeded $688 million nationwide last year, with Texas reporting major increases in fraudulent activity.
Under Texas law, theft of mail from fewer than 10 people can result in a Class A misdemeanor charge, while larger-scale offenses or possession of stolen mailbox keys can lead to felony charges.
Officials encourage residents to collect mail promptly, use indoor postal drop boxes when possible, enroll in USPS Informed Delivery services, and report suspected mail theft to law enforcement or the U.S. Postal Inspection Service at 1-877-876-2455.
