The arrest of a League City mail carrier on Thursday, Aug. 20, came just one day after federal prosecutors unsealed a separate $23 million stolen-check conspiracy involving three Houston-area postal workers.

Richard Ybanez, 46, of Bacliff was taken into custody at approximately 3:22 p.m. in the parking lot of a convenience store in the 1600 block of West League City Parkway. He was still in uniform and in front of his USPS vehicle at the time of the arrest, according to ABC13.

Ybanez was charged with mail theft of 10 to 30 items, a state jail felony. His bond was set at $5,000.

The League City Police Department's Special Investigations Unit worked with agents from the U.S. Postal Service Office of Inspector General on the case, which began about a week before the arrest after authorities received a tip, according to the LCPD press release. Police did not disclose what type of mail was allegedly stolen or where the suspected thefts occurred.

Federal indictment alleges $23M check theft ring

The two cases are not connected. But the timing underscores a pattern.

One day before Ybanez's arrest, a federal grand jury in the Southern District of Texas indicted five people in a far larger mail theft operation. Prosecutors allege the ring stole checks totaling approximately $23,973,338.15 over a period beginning in October 2022.

The five defendants are Tryston Tremaine Vaughn, Catherine Kilpatrick, Drakkor Jamar Alexander, Malcolm Tiree Joubert and Alyssa Nadine Bryant. Three of them, Kilpatrick, Alexander and Joubert, worked as USPS mail carriers in the Houston area, according to the federal indictment.

Prosecutors say Vaughn recruited the carriers to steal checks from their routes. The stolen checks were then posted for sale on a Telegram channel called "slipsandchips" and shipped to buyers via FedEx, targeting accounts at Chase Bank, Stellar Bank, Amegy Bank, Citibank and BMO Bank.

The largest single check identified in the indictment was worth $1,517,875.27, allegedly stolen by Joubert from a BMO Bank account in May 2024.

Kilpatrick appeared before a federal judge in handcuffs on Tuesday, Aug. 25, and pleaded not guilty during her initial appearance.

All five defendants face charges of conspiracy to commit bank fraud and multiple bank fraud counts. The three postal carriers also face charges of theft of mail matter by a postal employee. If convicted, prosecutors intend to seek forfeiture of property connected to the alleged offenses.

What it means for League City residents

The federal case is unrelated to Ybanez's arrest, according to ABC13's reporting. However, both cases raise mail security concerns for residents along affected routes.

ABC13's investigative unit found that at least 13 cases of mail theft by postal employees were reported in Galveston County between January 2021 and February 2026.

The LCPD said its partnership with the USPS Office of Inspector General remains central to identifying and addressing criminal activity affecting the League City community.

No next court date has been announced for Ybanez's state case. The federal investigation into the five-person ring remains ongoing.
