Wilmer, a small but fast-changing city just south of Dallas, got hit with another political shock yesterday when two of its top officials were arrested in the same criminal investigation. Newly sworn-in council member Moses Garcia and Acting Police Chief Jesus Mancillas were taken into custody, leaving the five-member council and residents scrambling to figure out who is actually in charge. The turmoil lands at a sensitive moment as local leaders try to manage a wave of industrial growth while already dealing with recent political shake-ups.
According to an arrest affidavit obtained by NBC 5 DFW, Garcia was arrested Monday and charged with misdemeanor terroristic threat after an incident at a Shell station just off Interstate 45. The affidavit says Garcia got into a heated verbal confrontation inside the convenience store and that a Wilmer police sergeant who later reviewed surveillance footage could hear Garcia yelling, making threats and using racially derogatory language. The documents also state that Garcia told others he was responsible for the recent removal of the city's police chief and mayor.
Garcia had only recently arrived on the council after winning a seat in May. He ran on a platform calling for tighter rules on the rapid build-out of data centers and warehouses in and around Wilmer, KERA reported. That industrial boom has become a major flashpoint in local politics as the city looks to capture new revenue from logistics and tech infrastructure. Garcia's election and his push to rein in development had already shifted dynamics on the small council before his arrest added a fresh layer of uncertainty.
The same affidavit also identifies Mancillas as a suspect in the case. He was charged with interfering with public duties after investigators say he tried to obtain the station's surveillance video and “take over” the investigation, according to NBC 5 DFW. Both men bonded out of the Dallas County Jail on Monday afternoon. The city released a statement acknowledging the arrests and pledging to cooperate with authorities. Dallas County Commissioner John Wiley Price told NBC 5 that the rapid turnover at city hall and the new criminal charges risk undercutting Wilmer's recent economic momentum.
Legal snapshot
Garcia was booked on a terroristic-threat charge, a count that the affidavit describes as involving behavior prosecutors say was intended to frighten or intimidate. Under Texas law, terroristic threat is defined in Penal Code §22.07 and can be filed as either a misdemeanor or a felony, depending on who is targeted and the impact of the threat. Mancillas, meanwhile, faces a charge of interference with public duties, tied to his alleged effort to seize potential evidence from the store. That offense is spelled out in Penal Code §38.15, which generally requires more than speech alone and is usually treated as a misdemeanor.
What's next for the city
The arrests deepen a leadership vacuum that opened earlier in the month when Mayor Sheila Petta stepped down after six years in office, KERA reported. With a population estimated at roughly 6,700 people, according to U.S. Census QuickFacts, Wilmer now finds its small council facing big decisions. Members must decide whether to appoint a new mayor or call a special election, all while trying to keep public safety, city services and economic development on track. For now, the interim city administrator has said Wilmer will cooperate with investigators as municipal leaders and residents wait to see how this latest crisis plays out.
