Sonya Camargo Marin, 41, was in the McLennan County Jail Friday charged with two counts of aggravated assault with a deadly weapon after an argument over access to an ATM next to a Bellmead convenience store led to an argument and ultimately a fight.

Bellmead officers responded Thursday to a report of a fight in progress at the ATM along northbound Interstate 35, and when they arrived found that “multiple subjects were yelling and a physical altercation was occurring,” police said in a press release Friday.

Officers determined that Marin and her son were in one vehicle at the ATM and that a 23-year-old man and his 21-year-old wife were in another.

“During the verbal argument Marin displayed a box cutter in a threatening manner to the victims,” Bellmead police Lt. Kory Martin said.

“The male victim and Marin’s son worked together to disarm Marin,” he said, but the fight continued, injuring the man’s wife.

Paramedics treated the victims at the scene.

Marin’s bonds total $10,000.
