The documents obtained by ABC-7 indicate that one of the brothers allegedly told police they were firing the guns because they were celebrating their father's birthday.

Police have identified the two borthers they took into custody last week as 21-year-old Josue Macias and 23-year-old Ruben Macias. The pair were arrested and charged with discharging a firearm within city limits.

According to the court documents, the two men fired guns along a three-mile stretch of U.S. 54 northbound between Transmountain and Sean Haggerty.

The video of the gunfire first appeared on a local social media page and was quickly shared by many. It showed two men firing shots out of car windows along the freeway. The viral video prompted a police probe that led to the arrests.

Police said they determined the gunfire depicted in the viral video took place on Nov. 17.
