A Wilmer city council member and the city’s acting police chief were arrested and booked into the Dallas County jail on Monday, stemming from an incident at a convenience store on July 22. Moses Garcia, 53, was charged with making a terroristic threat, a class B misdemeanor, for allegedly physi cally threatening an individual and making racially derogative verbal comments, according to an arrest affidavit. Garcia was elected as a city council member in May 2026. A Wilmer police sergeant took a written complaint from an individual after the incident and then reviewed surveillance video from a Shell station. According to the arrest affidavit, Garcia referred to himself in a profane manner “and made statements claiming responsibility for removing the City’s Police Chief, Mayor, and other city personnel,” the affidavit reads. “Garcia continued making statements indicating he had influence and authority within the City.” A separate arrest warrant for Jesus Mancillas, 57, states Wilmer’s acting Chief of Police interfered with the investigation into Garcia’s conduct by taking custody of the surveillance video and directing that he would personally complete the investigation. “At the time of the interaction, Mancillas was not wearing a police uniform, was not displaying a badge, was not carrying a department-issued sidearm, and did not display any other visible indication that he was acting as a commissioned peace officer,” the affidavit reads. Manciallas was charged with interference with public duties, a Class B misdemeanor. Frank Posada, the Wilmer Interim City Administrator, told NBC 5 in a statement he was aware of the arrests of both men, who bonded out of the Dallas County jail Monday afternoon. While refraining from commenting further on Garcia’s arrest, he did express disappointment with Mancilla’s involvement. “Last week, I appointed Mr. Mancillas to serve as Acting Police Chief to provide leadership and operational oversight of the Police Department during an ongoing administrative matter involving the Police Captain,” Posada said. “I had no knowledge that the Wilmer Police Department was contemplating or carrying out an arrest involving Mr. Mancillas. He was assisting the City of Wilmer at my request, and I am disappointed by what has occurred.” Dallas County Commissioner John Wiley Price, whose district includes several municipalities, said he’s concerned with how the city has been governed over the last few months. “The city is running amok right now,” Price said Monday. “Just seems like the city hit reverse, and it’s a sad day.” Price pointed to the resignation of several city leaders, including former Mayor Sheila Petta on July 10, as negative developments for the city of just over 7,000 residents that has seen an economic uptick in recent years with more businesses locating along it’s I-45 corridor. Petta on Monday told NBC 5 she resigned for health reasons and what she saw as growing dysfunction on the 5-member city council since Garcia took office in May. “This is not good for the city of Wilmer,” Petta said after learning of the criminal charges Monday. ...read more read less
