Authorities arrested two San Marcos residents Wednesday for allegedly defacing a Texas landmark with their own nicknames in March, according to a news release issued by the City of San Marcos.

Charles Agawereh, 24, and Meredith Baird, 21, of San Marcos, were arrested on a state jail felony charge for graffiti and were booked into Hays County Jail. They face up to two years in prison for the charge, according to Texas Parks and Wildlife Department.

The two allegedly used a substance appearing to be spray paint on March 20 on the south face of the summit at the Enchanted Rock State Park near Fredericksburg. They were caught on camera after the incident took place, according to the news release.

The graffiti read, “Ca$h” and “Truck,” as seen in the photos above. Those photos were shared on social media, which ultimately led to the two people's arrest, according to the release. But it was the words that apparently game them away, according to a release from the city of San Marcos.

A San Marcos detective identified Agawereh and Baird because he knew that "Ca$h" and "Truck" were the couple's nicknames due to a previous arrest, the release said.

The police had searched Agawereh's apartment in January and saw papers with both nicknames "Ca$h" and "Truck." Once that information was passed along to Texas Parks and Wildlife law enforcement, authorities searched Agawereh's and Baird's home again Wednesday, April 6.

The couple also faces charges of possession of marijuana, amphetamine pills and ecstasy found in the apartment, according to a release from San Marcos.
