CUMMING — Two construction workers face charges for their roles in a fight Tuesday afternoon at the site of the new Costco.

According to Cumming police, Ernesto Gomez Garcia, 49, of Tucker has been charged with aggravated assault, a felony, while 22-year-old Adan Rivera faces one count of battery, a misdemeanor.

Bryan Zimbardi, a spokesman for Cumming police, said three men were involved in “some kind of physical altercation” at the property off Market Place Boulevard and Bald Ridge Marina Road near Ga. 400 at Exit 15.

According to Zimbardi, Garcia cut 21-year-old Jairo Rivera Rodriguez with a trowel, and Rodriguez head-butted him.

In the aftermath, Rodriguez was taken to Northside Hospital-Forsyth, where authorities said he received 12 stiches to close a wound from the trowel.

According to Zimbardi, the fight broke out after Rodriguez urinated on the floor of the construction site, angering Garcia.

Rivera, Rodriguez’s brother, then joined in the fight and received minor wounds that did not require a trip to the hospital, Zimbardi said.

Costco is expected to open Aug. 29.
